This change optimizes rx reorder queue setup by using
tid_bitmap, which contains a group of tids, to set up
multi tids at a time instead of one tid after another.

Currently when processing the WBM error entries, if there
is an nbuf sanity check failure, i.e. paddr in the srng
entry does not match the paddr from the rx_descriptor, then
the rx_desc flag "unmapped" is being set, without the nbuf
being unmapped and the rx_desc is getting added to the freelist.
This results in the rx_descriptor being replenished with a
new buffer, and the existing nbuf is leaked (without being unmapped).
In order to fix this issue, do not modify any fields of the
rx_desc, since it will be moved to err_state, due to the
sanity failure. Also this rx_desc will not be added to the
freelist, since it should not be replenished due to err_state.

Originally Change-Id: I9fa71bdb6d4e4aa93fc795cc5dd472a181325991
was brought in to fix a race condition between Rx buffers
map/unmapped in dp_ipa_handle_rx_buf_smmu_mapping() and at the
same time map/unmapped from dp rx replenish context.
The fix ensured that rx_desc is unmapped and rx_desc->unmapped=1
flag will be set atomically within a lock.
But Change-Id: Iadb40071fb733cc4de3291784df5075d5a099a8e
introduced a flaw by releasing the lock before setting the flag to 1.
This is currently causing race condition and causing double
unmap calls when IPA smmu pool unmap and dp_rx_replenish unmap
is running in parallel. This change will fix this issue, by setting
the flag before the lock is released.

done the following changes to improve the RX path KPI
1. remove the extra invalidate in RX path as
we no longer dirty the RX TLV cache lines.
we now store the rx error codes in nbuf cb instead
of RX TLVs reserved memory bytes.
2. with features like flow tag and wds extended mode
enabled by default, the rx_fast_flag is always set
to false, this resulted in lot more instructions
being executed in RX path.
Now we ensured this flag is at least set for other
features which are not enabled by default.

treated as an eapol frame and gets dropped in

In case of where multiple scatter gather frames are
part of same MPDU last_mpdu_in_msdu will be set only
for last buffer of last scatter frame in MPDU.
Below is the hw descriptors bits when 2 scatter frames
are part of a MPDU
-----------------------------------------------------------
|Buffer_num | MSDU_NUM | first_in_mpdu | cont | last_in_mpdu |
-----------------------------------------------------------
| 1 | 1 | 1 | 1 | 0 |
-----------------------------------------------------------

In above case scatter MSDU boundary checks can be done only
based on continuation bit. So while reaping use continuation
bit instead of last_in_mpdu bit to detect boundary

In BE architecture, HW provides the support for basic vdev stats and

Avoiding per packet stats updation reduces CPU load and improves KPI.
