For sdio chip, if the rssi is not good, then it have some retry,
firmware will indicate the msdu list of a ppdu with a hole, it
means it lost the hole msdu, after the msdu retry from AP, the
hole msdu will indicate from firmware later. The hole msdu's PN
check will fail and the hole msdu will be dropped.
PN check fail example:
Sequence number PN number PN check status
3814 6101 success
3815 6102 success
3816 6103 success
3818 6105 success
3819 6106 success
3820 6107 success
3817 6104 fail
The correct logic is reorder the msdu list and then do PN check.
ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic
and then do PN check in ieee80211_rx_h_decrypt of mac80211.
example after reorder:
Sequence number PN number PN check status
3814 6101 success
3815 6102 success
3816 6103 success
3817 6104 success
3818 6105 success
3819 6106 success
3820 6107 success
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00017-QCARMSWP-1.

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 Restructured Text 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.
