The commit <52edc17f94f7bd4d9> ("bugfixes and new hardware support for arcnet driver") adds fixes for the packet length calculations in arc-rawmode. As the capmode protocol is derived from the arc-rawmode code, the capmode also needs the fixes. rx(): - Fixed error in received packet lengths; 256 byte packets were being received as 257 bytes packets. prepare_tx(): - Fixed error in transmit length calcs; 257 byte packets were being transmitted as 260 byte packets.
