From d56d453a1dd85aff08fe6965f395049725fdb04e Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Fri, 6 Jun 2008 22:54:08 +0200 Subject: [PATCH] rt2x00: Cleanup struct skb_frame_desc. The data and data_len fields aren't really necessary in struct skb_frame_desc, as they can be deduced from the skb itself.
