net/pfstat on -current

[Dorian Büttner]

Hi,

rebuilt some machines to -current as called for testing. I then found 
pfstat complaining steadily like this:

ioctl: DIOCIGETIFACES: Operation not supported by device
pf_query: query_ifaces() failed

A rebuild of the port against -current fixed this, however I just thaught I'd 
throw this in since I'm not sure if it needs special treatment like an entry
on current.html or so (would help planning an upgrade to 4.7?)

out-of-date simply showed net/pfstat,-main               # c.53.0 -> c.53.1

Cheers,
Dorian
