Subject: [PATCH AUTOSEL 4.14 40/87] ath10k: sdio: set skb len for all rx
 packets

From: Alagu Sankar <alagusankar@...ex-india.com>

[ Upstream commit 8530b4e7b22bc3bd8240579f3844c73947cd5f71 ]

Without this, packets larger than 1500 will silently be dropped.
Easily reproduced by sending a ping packet with a size larger
than 1500.
