[PATCH] fwd: Squash different-signedness comparison warning

[PATCH] fwd: Squash different-signedness comparison warning

[David Gibson]

On certain architectures we get a warning about comparison between
different signedness integers in fwd_probe_ephemeral().  This is because
NUM_PORTS evaluates to an unsigned integer.  It's a fixed value, though
and we know it will fit in a signed long on anything reasonable, so add
a cast to suppress the warning.
