Hi Daniel,
thx for the review.
[...]
The design is very similar for most of the Intel drivers. Why the inconsistency
on
ice driver compared to the rest, what's the rationale there to do it in one but
not
the others? Generated code better there?
I applied the same logic for the ice driver but the code is just
slightly different.
Couldn't you even move the 'unsigned int offset = xyz_rx_offset(rx_ring)' out
of the
while loop altogether for all of them? (You already use the xyz_rx_offset()
implicitly
for most of them when setting xdp.frame_sz.)
We discussed moving "offset = xyz_rx_offset(rx_ring)" out of the while
loop before but Saeed asked to address it in a dedicated series since
it is a little bit out of the scope. I have no strong opinion on it,
do you prefer to address it directly here?
Fair enough, I might have preferred it in this series as part of the overall
cleanup,
but if you plan to follow up on this then this is also fine by me. Applied the
v5 to
bpf-next in that case, thanks!
