Subject: [PATCH rdma-next 6/6] RDMA/ipoib: Add support for XDR speed in ethtool

From: Patrisious Haddad <phaddad@...dia.com>

The IBTA specification 1.7 has new speed - XDR, supporting signaling
rate of 200Gb.

Ethtool support of IPoIB driver translates IB speed to signaling rate.
Added translation of XDR IB type to rate of 200Gb Ethernet speed.
