Message-Id: <20161220151430.11115-1-suresh.reddy@broadcom.com> Date: Tue, 20 Dec 2016 10:14:30 -0500 From: Suresh Reddy <suresh.reddy@...adcom.com> To: netdev@...r.kernel.org, kalesh-anakkur.purayil@...adcom.com Subject: [PATCH net] be2net: Increase skb headroom size to 256 bytes From: Kalesh A P <kalesh-anakkur.purayil@...adcom.com> 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.
