[Intel-wired-lan] [PATCH v5 intel-next 9/9] ice: make use of ice_for_each_* macros
Maciej Fijalkowski
maciej.fijalkowski at intel.com
Sat Aug 14 14:08:12 UTC 2021
Go through the code base and use ice_for_each_* macros. While at it,
introduce ice_for_each_xdp_txq() macro that can be used for looping over
xdp_rings array.
Commit is not introducing any new functionality.
