[v2] net/qede: support IOVA VA mode
Checks
Commit Message
Set RTE_PCI_DRV_IOVA_AS_VA in drv_flags. This allows initializing qede
PMD as non-root also on Linux v4.x, where /proc/self/pagemap can't be
acccessed without CAP_SYS_ADMIN privileges.
The flag was introduced generically but not in pmds in commit:
