b43: N-PHY: Fix the update of coef for the PHY revision >= 3case

2021-02-15T20:40:41+00:00

The documentation for the PHY update [1] states: Loop 4 times with index i If PHY Revision >= 3 Copy table[i] to coef[i] Otherwise Set coef[i] to 0 the copy of the table to coef is currently implemented the wrong way around, table is being updated from uninitialized values in coeff. Fix this by swapping the assignment around.

Kalle Valo says: ==================== wireless-drivers-next patches for v5.12 Second set of patches for v5.12. Last time there was a smaller pull request so unsurprisingly this time we have a big one. mt76 has new hardware support and lots of new features, iwlwifi getting new features and rtw88 got NAPI support. And the usual cleanups and fixes all over. Major changes: ath10k * support setting SAR limits via nl80211 rtw88 * support 8821 RFE type2 devices * NAPI support iwlwifi * add new FW API support * support for new So devices * support for RF interference mitigation (RFI) * support for PNVM (Platform Non-Volatile Memory, a firmware data file) from BIOS mt76 * add new mt7921e driver * 802.11 encap offload support * support for multiple pcie gen1 host interfaces on 7915 * 7915 testmode support * 7915 txbf support brcmfmac * support for CQM RSSI notifications wil6210 * support for extended DMG MCS 12.1 rate ==================== Signed-off-by: David S.

rtw88: replace tx tasklet with work queue

2021-02-12T07:51:09+00:00

Replace tasklet so we can do tx scheduling in parallel. Since throughput is delay-sensitive in most cases, we allocate a dedicated, high priority wq for our needs.

rtw88: add napi support

2021-02-12T07:50:58+00:00

Use napi to reduce overhead on rx interrupts. Driver used to interrupt kernel for every Rx packet, this could affect both system and network performance. NAPI is a mechanism that uses polling when processing huge amount of traffic, by doing this the number of interrupts can be decreased. Network performance can also benefit from this patch. Since TCP connection is bidirectional and acks are required for every several packets. These ack packets occupie the PCI bus bandwidth and could lead to performance degradation. When napi is used, GRO receive is enabled by default in the mac80211 stack. So mac80211 won't pass every RX TCP packets to the kernel TCP network stack immediately. Instead an aggregated large length TCP packet will be delivered. This reduces the tx acks sent and gains rx performance. After the patch, the Rx throughput increases about 25Mbps in 11ac.
