Subject: Don't send padding bytes for pings
X-Git-Url: http://git.bitcoin.ninja/index.cgi?p=rust-lightning;a=commitdiff_plain;h=cc6dd456faa878492f8f235b5d1770ca108271a6

Don't send padding bytes for pings

We (somewhat needlessly) send an extra 64 bytes with every ping.
While this isn't exactly a big deal, I saw it and figured we
shouldn't waste bytes on the wire given some of the constraints of
potential users.
