Rameshkumar Sundaram 7e48e3ddf9 wifi: ath12k: fix wrong handling of CCMP256 and GCMP ciphers 
[ Upstream commit f5d6b15d95 ]

Currently for CCMP256, GCMP128 and GCMP256 ciphers, in
ath12k_install_key() IEEE80211_KEY_FLAG_GENERATE_IV_MGMT is not set and
in ath12k_mac_mgmt_tx_wmi() a length of IEEE80211_CCMP_MIC_LEN is reserved
for all ciphers.

This results in unexpected drop of protected management frames in case
either of above 3 ciphers is used. The reason is, without
IEEE80211_KEY_FLAG_GENERATE_IV_MGMT set, mac80211 will not generate
CCMP/GCMP headers in TX frame for ath12k.
Also MIC length reserved is wrong and such frames are dropped by hardware.

Fix this by setting IEEE80211_KEY_FLAG_GENERATE_IV_MGMT flag for above
ciphers and by reserving proper MIC length for those ciphers.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
