-Subject: [PATCH 19/25] enic: fix Rx queue initialization after restarting a
- device
-
-If you stop then start a port that had already received some packets,
-the NIC could fetch discriptors from the wrong location. This could
-effectivly reduce the size of the Rx queue by a random amount and
-cause packet drop or reduced performance.
-
-Reset the NIC fetch index to 0 when allocating and posting mbuf
-addresses to the NIC.
-
-Fixes: 947d860c821f ("enic: improve Rx performance")
