From 80b60673ea598869050c66d95d8339480e4cefd0 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Wed, 29 Jan 2020 20:27:49 +1100 Subject: dp8393x: Always update RRA pointers and sequence numbers These operations need to take place regardless of whether or not rx descriptors have been used up (that is, EOL flag was observed). The algorithm is now the same for a packet that was withheld as for a packet that was not.
