It's hard to say why this is happening.

Why did you have to download the firmware? Doesn't your distro include
the binaries from linux-firmware.git?

The firmware you are using is version 16, but that kernel already
supports version -17.  I recommend you try to take the latest firmware
for the 7260 NIC from our copy of linux-firmware.git[2].

If this doesn't help, the best thing to do would be to report this as a
bug in bugzilla.kernel.org following the instructions in our wiki[1]. 
This way we can help you more easily.
