7260 will go. Not 5300.
Note that this code simulates Tx TCP Csum offload. I did that to write
the code while we still don't have the hardware that has this
capability. But for testing purposes, it should do the work. The
testing teams have reported that AP mode didn't work quite well with
this and I haven't taken the time to look into yet, but if you see
issues, please report them or even better: fix them :)

Right. These patches had a long internal review cycle. They are now
merge in our internal tree.
You can find them in our internal tree [1] (backport based). I will
push them soon in iwlwifi-next.git.
