This patch adds a handy column mask feature (-m) to net/trafshow, as
revised and submitted to me by Luigi Rizzo <firstname.lastname@example.org>.
Trafshow has not been updated by its author since 1998, so there is
little chance of this feature being incorporated into new versions.
Thus, I'll maintain it locally.
-m [src-ip M] [dst-ip M] [src-port M] [dst-port M]
Mask the specified field with mask M (which should
be specified as an hex number e.g. 0xffff0000)
before further processing of the packet. This
allows to aggregate traffic in the display to ease
The patch also bumps PORTREVISION appropriately.
