Subject: [PATCH v7 intel-next 9/9] ice: make use of ice_for_each_* macros
Date: Thu, 19 Aug 2021 14:00:04 +0200	[thread overview]
Message-ID: <20210819120004.34392-10-maciej.fijalkowski@intel.com> (raw)
In-Reply-To: <20210819120004.34392-1-maciej.fijalkowski@intel.com>

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.
