+netlink broken on big-endian mips
+
+Debian QEMU version 2.7.0, but the bug also appears in current git master (commit c36ed06e9159)
+
+As the summary says, netlink is completely broken on big-endian mips running qemu-user.
+
+Running 'ip route' from within a Debian chroot with QEMU simply hangs. Running amd64 strace on qemu-mips-static shows that it's waiting for a netlink response from the kernel which never comes.

+Notice the len in the buffer passed to the kernel is 0x28000000 which looks byteswapped.
+
+Removing the call to fd_trans_unregister in the NR_socket syscall in do_syscall fixes this for me, but I don't understand why the fd translation was immediately unregistered after being registered just before in do_socket - presumably it was added for a reason.
