Subject: [RFC] about "ipv6: tcp: fix flowlabel value in ACK messages send
 from TIME_WAIT"

Hi Florent 

make C=2 CF=-D__CHECK_ENDIAN__ net/ipv4/tcp_minisocks.o
...
net/ipv4/tcp_minisocks.c:303:46: warning: restricted __be32 degrades to integer

            tw->tw_flowlabel = np->flow_label >> 12;


np->flow_label is a __be32 (network byte order)

Not sure what is expected from this shift on a BE machine, I am guessing
this is not giving the expected result.

Thanks
