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.
