usr.sbin/tcpdump: print-ip.c print-ip6.c
Log message:
Catch up with the BPF_ALIGNMENT switch to the uint32_t.
bpf aligns data following the datalink header (e.g. ethernet)
on the BPF_ALIGNMENT boundary. Since rev1.41 of bpf.h it's
uint32_t instead of a long. And also since then almost all
packets become "unaligned" from the tcpdump perspective and
require costly copies into the internal buffer. Neither IP
header (struct ip) nor IPv6 (struct ip6_hdr) have fields
larger than 32 bits and therefore alignment requirements for
them are at most 32 bit.
