Subject: [PATCH] ath10k: fix latency issue for QCA988x
|
||||
Date: Thu, 29 Aug 2019 10:45:12 +0800
|
||||
|
||||
Bad latency is found on QCA988x, the issue was introduced by
|
||||
commit 4504f0e5b571 ("ath10k: sdio: workaround firmware UART
|
||||
pin configuration bug"). If uart_pin_workaround is false, this
|
||||
change will set uart pin even if uart_print is false.
|
||||
|
||||
Tested HW: QCA9880
|
||||
Tested FW: 10.2.4-1.0-00037
|
||||
|
||||

The signature of pci_disable_link_state was changed to indicate if the state

|

The skb_get_hash_perturb() function now takes a siphash_key_t instead of

an u32. This was changed in commit 55667441c84f ("net/flow_dissector:
|

switch to siphash"). Use the correct type in the fq header file

depending on the kernel version.

Subject: mac80211: fix scan when operating on DFS channels in ETSI domains
|
||||
|
||||
In non-ETSI regulatory domains scan is blocked when operating channel
|
||||
is a DFS channel. For ETSI, however, once DFS channel is marked as
|
||||
available after the CAC, this channel will remain available (for some
|
||||
time) even after leaving this channel.
|
||||
|
||||
Therefore a scan can be done without any impact on the availability
|
||||
of the DFS channel as no new CAC is required after the scan.
|
||||
|
||||
Enable scan in mac80211 in these cases.
