[PATCH] lance.c - dev_kfree_skb() then reference skb->len

From: Eli Carter (eli.carter@inet.com)
Date: Tue Nov 28 2000 - 13:08:16 EST


Greetings all,

Patch is against 2.2.17, drivers/net/lance.c.
I believe this to be "obviously correct," but please correct me if I'm
wrong.
This moves a reference to skb->len to before the possible
dev_kfree_skb(skb) call. Though it appears to work as is, I suspect it
is incorrect.

Please apply or let me know why.

Eli

ps. It's an attachment rather than inline because I can't seem to get
Netscape (4.71) to do that without replacing tabs with spaces. Grr.
