This patchset is new support in ionic for XDP processing,
including basic XDP on Rx packets, TX and REDIRECT, and frags
for jumbo frames.  This is the same set that we posted earlier
as an RFC, but now refreshed on the current net-next.

Since ionic has not yet been converted to use the page_pool APIs,
this uses the simple MEM_TYPE_PAGE_ORDER0 buffering.  There are plans
to convert the driver in the near future.

v3:
 - removed budget==0 patch, sent it separately to net

v2:
https://lore.kernel.org/netdev/20240208005725.65134-1-shannon.nelson@amd.com/
 - added calls to txq_trans_cond_update() (Jakub)
 - added a new patch to catch NAPI budget==0 (Jakub)

v1:
https://lore.kernel.org/netdev/20240130013042.11586-1-shannon.nelson@amd.com/

RFC:
