Exclude certain interfaces from transmitting with new flag #1
Would be very useful if one could exclude certain interfaces with a commandline flag from every being candidate to transmit a packet on, this flag is particularly useful in combination with -C, -L -E, -F or -N on boxes connected to an internet exchange.
I propose that the following:
will transmit LLDP packets on all interfaces in the system, except em0 and em1, even if it would receive a neighbor discovery packet on em0 and em1 (so -a does not apply to em0 and em1)
