Subject: Use a sizeof() in bgp_rt_prefix_print(). [skip ci]
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/db78c36113d827104a787fb6ac018ce9c193c07b?hp=c72751f8cdc8bf0f87d26531d24d74aaddf377f2

Use a sizeof() in bgp_rt_prefix_print(). [skip ci]

This way it is easier to see how the buffer is spent.
