From 17fa0b486bb728aa6b4d1a1f38a84fdf5ea86686 Mon Sep 17 00:00:00 2001 From: Kalesh A P Date: Tue, 20 Dec 2016 10:14:30 -0500 Subject: [PATCH] be2net: Increase skb headroom size to 256 bytes The driver currently allocates 128 bytes of skb headroom. This was found to be insufficient with some configurations like Geneve tunnels, which resulted in skb head reallocations. Increase the headroom to 256 bytes to fix this.
