>>2. New bugs:  True Scale qib bonding issue on RH 7.4, SLES 12.1 and 12.2 - Need update from Bill Schmidt (Intel)

Bug 2664<http://bugs.openfabrics.org/show_bug.cgi?id=2664> - Bonding doesn't work on RHEL 7.4

Bonding driver form RHEL 7.4 has integrated commit: https://github.com/torvalds/linux/commit/b5bf0f5b16b9c316c34df9f31d4be8729eb86845

This requires ipoib driver to return correct speed and duplex mode.  Commit adding this feature on ipoib driver:

https://github.com/torvalds/linux/commit/0d7e2d2166f6b0b7d1959ca858052a15feb574cc was added in 4.12 kernel, so it is missing from OFED 4.8 compat-rdma.

In consequence Bonding driver cannot retrieve required data and fails.

Bug 2665<http://bugs.openfabrics.org/show_bug.cgi?id=2665> - Bonding causes kernel panic on SLES 12.1 and SLES 12.2

Bonding driver from SLES 12.1/12.2 is missing kernel panic fix commit: https://github.com/torvalds/linux/commit/1533e77315220dc1d5ec3bd6d9fe32e2aa0a74c0

added in linux kernel 4.8. This makes it incompatible with ipoib drivers from OFED 4.8 compat-rdma.
