Adrian Chadd 4136c09143 The holding buffer logic needs to be used for _all_ transmission, not ... just "when the queue is busy." After talking with the MAC team, it turns out that the linked list implementation sometimes will not accept a TxDP update and will instead re-read the link pointer. So even if the hardware has finished transmitting a chain and has hit EOL/VEOL, it may still re-read the link pointer to begin transmitting again. So, always set ATH_BUF_BUSY on the last buffer in the chain (to mark the last descriptor as the holding descriptor) and never blank the axq_link pointer. Tested: * AR5416, STA mode TODO: * much more thorough testing with the pre-11n NICs, just to verify that they behave the same way. * test TDMA on the 11n and non-11n hardware.		2013-05-04 04:03:50 +00:00
