When we had a comeback, we will never use the default timeout values
again because comeback is never cleared.
Clear comeback if we send another association request which will allow
to start a default timer after Tx status.
The problem was seen with iwlwifi where the tx_status on the association
request is handled before the association response frame (which is the
usual case).
1) Tx assoc request 1/3
2) Rx assoc response (comeback, timeout = 1 second)
3) wait 1 second
4) Tx assoc request 2/3
5) Set timer to IEEE80211_ASSOC_TIMEOUT_LONG = 500ms (1 second after
round_up)
6) tx_status on frame sent in 4) is ignored because comeback is still
true
7) AP does not reply with assoc response
8) wait 1s <= This is where the bug is felt
9) Tx assoc request 3/3
With this fix, in step 6 we will reset the timer to
IEEE80211_ASSOC_TIMEOUT_SHORT = 100ms and we will wait only 100ms in
step 8.

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.
