From 960d6d08e395d5441d53caa21083c0b6d38995f9 Mon Sep 17 00:00:00 2001 From: Zhaoyang Liu Date: Fri, 13 Mar 2015 17:37:59 +0530 Subject: mwifiex: delay skb allocation for RX until cmd53 over This patch moves SKB allocation for RX packets from current place i.e. after reading MP regs to place where we already have read data from SDIO bus ie after cmd53. mp_rx_aggr_setup has been modified accordingly to set skb_arr to NULL.
