Fixed by: commit dcbcdf22f500ac6e4ec06485341024739b9dc241 Author: Randy Dunlap <randy.dunlap@...cle.com> Date: Thu Mar 10 13:45:57 2011 -0800 net: bridge builtin vs. ipv6 modular When configs BRIDGE=y and IPV6=m, this build error occurs: br_multicast.c:(.text+0xa3341): undefined reference to `ipv6_dev_get_saddr' BRIDGE_IGMP_SNOOPING is boolean; if it were tristate, then adding depends on IPV6 || IPV6=n to BRIDGE_IGMP_SNOOPING would be a good fix. As it is currently, making BRIDGE depend on the IPV6 config works. Reported-by: Patrick Schaaf <netdev@....de> Signed-off-by: Randy Dunlap <randy.dunlap@...cle.com> Signed-off-by: David S.
