Re: [B.A.T.M.A.N.] [PATCH] batman-adv: Ensure that eth_type_trans gets linear memory

eth_type_trans tries to pull data with the length of the ethernet header from the skb. We only ensured that enough data for the first ethernet header and the batman header is available in non-paged memory of the skb and not for the ethernet after the batman header.

eth_type_trans would fail sometimes with drivers which don't ensure that all there data is perfectly linearised.

Ok, I went ahead and applied this patch in revision 1874 after some discussion. No Intel user needs to suffer if we can avoid it. ;-)
