CVS commit: src/sys/dist/ipf/netinet

[Greg Troxel <gdt%netbsd.org@localhost>]

Module Name:    src
Committed By:   gdt
Date:           Thu Jul 19 14:04:34 UTC 2007

Modified Files:
        src/sys/dist/ipf/netinet: fil.c ip_fil.h

Log Message:
Avoid casting to "i6addr_t *", because that type requires 64-bit
alignment and nothing guarantees that IPv6 packets in mbufs are 8-byte
aligned.  gcc was coalescing adjacent 32-bit compares into "ldx" on
sparc64, leading to alignment faults when processing icmp6 arriving on
gif with IPv4 outer addresses.

Fix mostly from darrenr@.  Discussed extensively on port-sparc64.
