This definition was just copied from the xpp driver. DAHDI-253 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6550 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-04-29wctc4xxp: Change netif_rx_xxx to napi_xxxShaun Ruffell
The netif_rx_xxx functions were dropped from the linux kernel source on 2009-01-21 in commit 288379f050284087578b77e04f040b57db3db3f8. (closes issue #14963) Reported by: tzafrir git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6526 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-03-24Do not allocate more memory than is needed when sending packets.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6245 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-24Block runt packets from the transcoder.Shaun Ruffell
Tested by: Walter Klomp git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6244 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-24Do not define the debug flags if CONFIG_SLUB is not set.Shaun Ruffell
Some versions of the kernel (2.6.18-92.1.22.el5) have patches in them to panic if a slab cache is created with unsupported flags. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6237 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Make some messages debug messages and minor formatting adjustment.Shaun Ruffell

2009-03-23Verify checksum on the RTP IP header before queueing.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6227 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Poll the card in a kernel timer when several channels are open.Shaun Ruffell
Polling the driver increases overall system throughput when there are several transcoding channels open by reducing the number of interrupts the the TC400M generates. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6226 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Optionally show total number of packets dropped when channel is closed.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6225 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Do not handle duplicate reponses.Shaun Ruffell
It is possible for system activity to prevent the wctc4xxp driver from responding the the firmware on the TC400M for a period of time. If this occurs, the TC400M will resend a response to a command that we sent. This duplicate reponse will then sometimes confuse the driver. Normally this would manifest as an attempt to connect the same channel together in a transcoding session. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6224 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Create our own free list for commands instead of using kmem_cache.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6223 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Set TX_COMPLETE atomically with changes to the waiting_for_response_list.Shaun Ruffell
This change is to catch a condition where it is possible, for whatever reason, for a response to come in before the request is marked tx complete. If this happened, it was possible to leak the response packet and double complete the command. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6222 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23split send_trans_connect into a connect / disconnect pair.Shaun Ruffell
Trivial change that makes the code read more naturally. Also changes the order of members in the channel_pvt structure. For more natural alignment. Both non-functional changes. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6221 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23If the driver fails to register, make sure we cleanup the command cache.Shaun Ruffell
git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6220 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Setup the TC400M to poll the own bit on the descriptor ring.Shaun Ruffell
On certain systems having the hardware poll the descriptor ring provides more reliable operation that strobbing the transmit demand poll and receive demand poll register. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6219 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Make sure that messages sitting in the outbound queue cause the timer toShaun Ruffell
reschedule. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6218 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-03-23Refactor channel command handling.Shaun Ruffell
Makes commands and reponses clearer and easier to trouble shoot, reduces pressure on the stack, and brings driver closer to kernel coding standards. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6217 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2009-01-27And once again I'm reminded why I should always compile before committing.Shaun Ruffell

Closes issue #14285 . Reported by: tzafrir git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5842 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2009-01-27- When tearing down channels, use the channel's timeslot as the index into theShaun Ruffell
encoder and decoder arrays, and not the channel which is returned from the DTE. Issue: DAHDI-231. - Instead of completely servicing the receive descriptor ring in the workqueue, have the interrupt handler queue them up for the workqueue. - No need to interrupt on both transmit and receive since we expect a response to every packet we send. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5835 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-12-01Service the transmit descriptor ring before the receive descriptor ring soShaun Ruffell
that commands that are still sitting on the transmit descriptor ring are not completed twice. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5413 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2008-11-17- Fix for race condition of encoder and decoder are allocated at the same timeShaun Ruffell
in the driver. This would result in -EBUSY returns from the DAHDI_TC_ALLOCATE ioctl. - Increase the length of the receive descriptor ring from 8 to 32 to reduce the probability of running out of receive descriptors. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5321 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-10-28fix a large number of warnings found by sparse, the kernel code sanity ↵Kevin P. Fleming
checking tool. some of these fixes are non-optimal (casting 'unsigned long' to '__user void *'), but are unavoidable in many cases. started from tzafrir's patch, did most of the work myself.

2008-10-10- Ensure that the source format is considered when selecting a transcoder.Shaun Ruffell
- When a command is to be retried, turn off the TX_COMPLETE flag before resubmitting it to the hardware. This should elimate some of the warnings printed to the kernel log in the wctc4xxp_transmit_cmd function. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5084 a0bf4364-ded3-4de4-8d8a-66a801d63aff
2008-10-06Embed room for the complete packet to the DTE in the transcoder bufferShaun Ruffell
structure. Simplifies alignment management at the cost of a little wasted memory, but the end results is that operation is more reliable on more systems. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5060 a0bf4364-ded3-4de4-8d8a-66a801d63aff

2008-10-02Keep hold of the channel lock when setting the data_ready flag for the channelShaun Ruffell
after writing to the receive queue. Prevents a warning that data was on the recieve queue but the data ready flag was not set. Issue: DAHDI-42 git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@5030 a0bf4364-ded3-4de4-8d8a-66a801d63aff
