If drivers want to support S/G (really just gather DMA on TX) then we can now easily support this on the fast-xmit path since it just needs to write to the ethernet header (and already has a check for that being possible.) However, disallow this on the regular TX path (which has to handle fragmentation, software crypto, etc.) by calling skb_linearize(). Also allow the related HIGHDMA since that's not interesting to the code in mac80211 at all anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com> |
