Subject: [RFC v2 0/1]: Add minimum bandwidth support in IP tool.

Today IP tool allows configuring only maximum bandwidth.
Likewise minimum bandwidth can also be configured for a VF. It puts
lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth
of at least this value.

With this change, user can alter minimum bandwidth rate.

This patch series has 1 combined patch that adds required support in kernel
and qlcnic driver changes for minimum bandwidth support.

This change also requires changes in IP tool. I am sending that patch
separately.

Changes in v2 per suggestions from Ben Hutchings and Michal Kubecek:

   net patch:
        o Fixed enum index for IFLA_VF_RATE
        o ndo_set_vf_rate replaces ndo_set_vf_tx_rate. Drivers that currently implement
          ndo_set_vf_tx_rate is converted to implement ndo_set_vf_rate instead.
        o If only IFLA_VF_TX_RATE is specified, the core should get the current minimum
          before calling ndo_set_vf_rate.
        o IFLA_VF_RATE should override if both IFLA_VF_RATE and IFLA_VF_TX_RATE are specified.
        o Combined qlcnic patch to add support for minimum bandwidth with net patch


Please comment.

Thanks,
Sucheta.
