qtnfmac: lock access to h/w in tx path

2017-09-20T12:35:32+00:00

Fix tx path regression. Lock should be held when queuing packets
to h/w fifos in order to properly handle configurations with
multiple enabled interfaces.

qtnfmac: fix free_xfer_buffer cleanup

2017-08-31T12:57:39+00:00

Check if skb tracking arrays has been already allocated. This additional
check handles the case when init partially failed.

qtnfmac: modify qtnf_map_bar not to return NULL

2017-08-31T12:57:39+00:00

NULL is not a special type of success here but a error pointer.
So it makes sense to check against NULL in qtnf_map_bar
and return error code.

qtnfmac: module param sanity check

2017-08-31T12:57:38+00:00

Linux built-in circ_buf implementation assumes that that the
circular buffer length is a power of 2. Make sure that
rx and tx descriptor queue lengths are power-of-2.

qtnfmac: drop -D__CHECK_ENDIAN from cflags

2017-08-31T12:57:37+00:00

Flag -D__CHECK_ENDIAN was wrong: it should be -D__CHECK_ENDIAN__ instead.
However now this flag is enabled by default, so it can be removed.

qtnfmac: modify tx reclaim locking

2017-08-17T07:05:07+00:00

Perform additional reclaim from qtnf_pcie_data_tx. Lock tx_lock serves only
reclaim synchronization purposes. Rename it accordingly and improve
granularity moving this lock to qtnf_pcie_data_tx_reclaim.

qtnfmac: switch to kernel circ_buf implementation

2017-08-17T07:05:04+00:00

Current code for both Rx and Tx queue management is a custom and incomplete
circular buffer implementation. It makes a lot of sense to switch to kernel
built-in circ_buf implementation.
