RSTP testing - PATCH: BPDU length calculation
The bpdu_len sent to STP_OUT_tx_bpdu() excludes the ethernet and
and LLC headers, though the bpdu pointer points to the start of the
ethernet header. Given the types in rstplib/stp_bpdu.h, we need to
be sending a packet with (base, len) given by
(bpdu, bpdu_len + sizeof(MAC_HEADER_T) + sizeof(ETH_HEADER_T))
MAC_HEADER_T is dest and source ethernet addresses and ETH_HEADER_T
is the 802.2 part.
