Two issues introduced by my recent asynchronous filter handling changes:
1. The old filter_rfs_insert would replace a matching filter of equal
priority; we need to pass the appropriate argument to filter_insert to
make it do the same.
2. It's possible to cause the kernel to hammer ndo_rx_flow
Necessary to allow redirecting a flow when the application moves.

Status checking in xfrm_input doesn't cover CRYPTO_GENERIC_ERROR and
CRYPTO_INVALID_PACKET_SYNTAX.
Given patch adds additional check for CRYPTO_INVALID_PACKET_SYNTAX and
treats CRYPTO_GENERIC_ERROR as status matching LINUX_MIB_XFRMINERROR.

default.
As setting net.ipv6.conf.default.accept_ra via sysctl.conf or similar
