Subject: [PATCH] [NET] Add constant for FCS/CRC length (frame check sequence)

From: Auke Kok <[email-masked]>
Date: Tue, 15 May 2007 15:29:16 -0700

From: Auke Kok <[email-masked]>

About a dozen drivers that have some form of crc checksumming or offloading
use this constant, warranting a global define for it.
