Oh, of course, I mean, what do you have in td->td_ucred?
[Sreenivas] not sure, I referred to socreate() usage in the kernel source a=
nd used it.
One more observation. Interface "cxgbe1" has a IPv6 interface and an IPv4 i=
nterface, print in ifa_ifwithaddr_internal () shows like below
ifp->xname:cxgbe1 ifp->dname:cxgbe
ifa->ifa_addr->sa_family:18 addr->sa_family:28 =3D=3D> this is for AF_LINK
ifa->ifa_addr->sa_family:2 addr->sa_family:28 =3D=3D> for AF_INET
Though cxgbe1 has a IPv6 interface there is no entry for AF_INET6
Interface "cxgbe3" is not configured with any IP, print in ifa_ifwithaddr_i=
nternal () shows like below
ifp->xname:cxgbe3 ifp->dname:cxgbe
ifa->ifa_addr->sa_family:18 addr->sa_family:28 =3D=3D> for AF_LINK
