Subject: Allocate a persistent packet buffer.
X-Git-Url: http://git.meshlink.io/?a=commitdiff_plain;h=d41728102f197003c7db2db6f679e1ca5e26535d;hp=d41728102f197003c7db2db6f679e1ca5e26535d;p=utcp

Allocate a persistent packet buffer.

Instead of allocating a new packet buffer every time we generate a packet,
we pre-allocate it and keep it around. We only reallocate when the MTU
increases.
