From 2c11ab90067a8bb9d7dca3e65ace950fcd9c2f1b Mon Sep 17 00:00:00 2001 From: Cathy Luo Date: Thu, 12 Mar 2015 01:29:31 -0700 Subject: [PATCH] mwifiex: fix a bug in Rx multiport aggregation logic It's been observed Rx aggregated packets are always followed by a single Rx packet. This patch improves our logic to add that extra packet in next aggregation.
