Subject: [PATCH net 1/3] Drivers: net: hyperv: Allocate memory for all possible per-pecket information
Date: Tue, 8 Apr 2014 12:46:09 -0700 [thread overview]
Message-ID: <1396986371-12137-2-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1396986371-12137-1-git-send-email-kys@microsoft.com>
An outgoing packet can potentially need per-packet information for
all the offloads and VLAN tagging. Fix this issue.
