The patch titled
Spidernet: remove ETH_ZLEN check in earlier patch
has been removed from the -mm tree. Its filename was
spidernet-remove-eth_zlen-check-in-earlier-patch.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Spidernet: remove ETH_ZLEN check in earlier patch
From: James K Lewis <jklewis@xxxxxxxxxx>
In an earlier patch, code was added to pad packets that were less that
ETH_ZLEN (60) bytes using the skb_pad function. This has caused hangs when
accessing certain NFS mounted file systems. This patch removes the check
and solves the NFS problem. The driver, with this patch, has been tested
extensively. Please apply.
