[dpdk-dev] [PATCH 1/3] net/enic: cleanup interrupt setup when stopping port

[Nelson Escobar]

enic_disable() wasn't calling rte_intr_disable() or
rte_intr_callback_unregister().  If stopping/starting a port, the
latter omission would result in the same interrupt callback being
registered multiple times, which would then cause it to be called
multiple times on every interrupt.

Fixes: fefed3d1e62c ("enic: new driver")
