3.5-stable review patch. If anyone has any objections, please let me know.

From: Ed Cashin <ecashin@xxxxxxxxxx>

[ Upstream commit 8babe8cc6570ed896b7b596337eb8fe730c3ff45 ]

In order for the network layer to see that AoE requires
no checksumming in a generic way, the packets must be
marked as requiring no checksum, so we make this requirement
explicit with the assertion.
