Merge branch 'mptcp-checksums'
Mat Martineau says:
====================
mptcp: Fix checksum byte order on little-endian
These patches address a bug in the byte ordering of MPTCP checksums on
little-endian architectures. The __sum16 type is always big endian, but
was being cast to u16 and then byte-swapped (on little-endian archs)
when reading/writing the checksum field in MPTCP option headers.
MPTCP checksums are off by default, but are enabled if one or both peers
request it in the SYN/SYNACK handshake.
The corrected code is verified to interoperate between big-endian and
little-endian machines.
Patch 1 fixes the checksum byte order, patch 2 partially mitigates
interoperation with peers sending bad checksums by falling back to TCP
instead of resetting the connection.
