See my posting yesterday to Linus, it's already in my net-2.6
tree and I already asked Linus to pull it in.

If you had submitted the build failure directly instead of privately
via Linus you would have been CC:'d and therefore be able to see all
of this. :-)

So the proper include (of net/ip.h) is there in ip_vs_xmit.c, but this
failure can also happen if CONFIG_INET is not enabled.

Are you doing that kind of test build?

This patch should fix that case, let me know if it works:


ipvs: Add proper dependencies on IP_VS, and fix description header line.

Linus noted a build failure case:

net/netfilter/ipvs/ip_vs_xmit.c: In function 'ip_vs_tunnel_xmit':
net/netfilter/ipvs/ip_vs_xmit.c:616: error: implicit declaration of function 'ip_select_ident'

The proper include file (net/ip.h) is being included in ip_vs_xmit.c to get
that declaration.  So the only possible case where this can happen is if
CONFIG_INET is not enabled.

This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS
entry.

Also, while we're here, remove the out of date "EXPERIMENTAL" string in the
IP_VS config help header line.  IP_VS no longer depends upon CONFIG_EXPERIMENTAL

This includes:

1) The bad IP_VS dependency randconfig build failure.

2) GRE tunnel rtnl_link initialization (bad memset size),
   from Herbert Xu.

3) External PHY detection fix in smc911x from Guennadi Liakhovetski.

4) E1000 VLAN feature flags should include TSO and CSUM offloads,
   from Patrick McHardy and ACK'd by Intel folks.

Please pull, thanks a lot!
