[dpdk-stable] [PATCH] net/iavf: fix queue interrupt for ICE

[Wei Zhao]

Enable CLEARPBA bit is required by ice NIC of A0/A1 version to
enable Tx and Rx queue interrupt.
Also enable CLEARPBA bit does no impact on IAVF behaviour when be
hosted by other devices, so we can make it as default.

Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt")
