This patch series addresses two issues I found with the 88E6341
switch, which likely also apply to the 88E6141 (which is the same
chip without AVB/TSN support).
The first was a genuine bug, which assumed the chip did not have
a dedicated ATU FID register (it does).
The other is an issue I noticed with hash collisions in the ATU.
I would appreciate some external testing before this commit is
reviewed, but I am including it as it was necessary for reliable
operation with multiple FIDs.
