From 6f258910733a8dbde368acc2ede4b8184ff0e09a Mon Sep 17 00:00:00 2001 From: Florin Malita Date: Sun, 4 Jun 2006 02:51:26 -0700 Subject: [PATCH] nmclan_cs: dereferencing skb after netif_rx() From: Florin Malita The skb may be gone after netif_rx(), we can't use 'skb->len' to update the stats. 'pkt_len' should work instead. Coverity CID: 911.
