Modified Files:
        src/sys/netinet: tcp_sack.c

Log Message:
Fix alignment problems causing regular panics in tpc_sack_option on
NetBSD/alpha and NetBSD/sparc. This fixes PR#34751.

The problem most likely started to show in gcc4 and is caused by the use of
a casting to an uint32_t pointer that is later copied from using memcpy.
Gcc detects the copying of 4 bytes from an uint32_t pointer and decides to
just replace it with an aligned copy causing the trap.

Fix provided by Izumi Tsutsui and ok'd by Martin.
