Ben Greear 4b1bbce9c3 ath10k: fix offchannel tx failure when no ath10k_mac_tx_frm_has_freq
[ Upstream commit cc6df017e55764ffef9819dd9554053182535ffd ]

Offchannel management frames were failing:

[18099.253732] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3780
[18102.293686] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3780
[18105.333653] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3780
[18108.373712] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3780
[18111.413687] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e36c0
[18114.453726] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3f00
[18117.493773] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e36c0
[18120.533631] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3f00

This bug appears to have been added between 4.0 (which works for us),
and 4.4, which does not work.

I think this is because the tx-offchannel logic gets in a loop when
ath10k_mac_tx_frm_has_freq(ar) is false, so pkt is never actually
sent to the firmware for transmit.

This patch fixes the problem on 4.9 for me, and now HS20 clients
can work again with my firmware.

Antonio: tested with 10.4-3.5.3-00057 on QCA4019 and QCA9888

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 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.
