Subject: [PATCH] raise NIC channels to number of threads

1.releases.grapheneos.org and 2.releases.grapheneos.org were ending up
with only 6 channels by default despite the hardware being capable of
far more. This raises it to match the 24 CPU threads.

0.releases.grapheneos.org is already using 32 channels by default which
matches the 32 CPU threads.
