HostAP processing of Ethernet FCS when in bridge mode

[Lewis Adam-CAL022]

A blast from the past.  I almost forgot about this issue.  It looks to me like the skb given to the hard_start_xmit routine in the driver definitely contains the fcs.  For a typical HTTP payload of 1500 bytes, hard_start_xmit receives 1504.  Is this something that might be hardware independent?  It definitely would not make sense to send the Ethernet FCS over the 802.11 link.  I am a bit confused on this one ...
