[ofa-general] [PATCH] opensm: enforce routing paths rebalancing on switch reconnection

[Sasha Khapyorsky]

When switch ports were reconnected we need to recalculate routing paths
balancing. Reconnection is detected by port state examination - when it
becomes INIT routing paths rebalancing (ignore_existing_lfts flag) is
enforced.
