Subject: i40e: Build for 64-bit targets only
|
|
|
|
i40e now uses cmpxchg64(), which only works on a 64-bit (or non-SMP)
|
|
system. It seems reasonable to expect that 40G hardware is not used
|
|
on 32-bit systems.
|
|
|
|
Fixes: 841c950d67c6 ("i40e/i40evf: use cmpxchg64 when updating private ...")
