After install x86 patch 101946-29, I have problems with sockets and

TCP/IP throughput.

These are two unrelated problems. To fix the socket problem, either
copy "sockmod" from an earlier kernel patch such as 101946-12 or
install patch 101946-35.

The performance problem is a device driver problem that doesn't
affect all ethernet cards. To fix this problem, you need to
install DU10 or later.
