be2net: fixup TX-rate setting code for Skyhawk-R
Skyhawk-R FW supports TX-rate setting only as a % value of the link speed, set via the SET_PROFILE_CONFIG cmd. This patch makes the necessary changes to the FW cmd descriptors to support the above change and also introduces checks in be_set_vf_tx_rate() to allow only discrete values (that map to % of the link-speed).
