  However, it is also not advancing data pointer by TX queue stats length, which would

This patch adds support to run Power On Self Test (POST) for 83xx adapters.
POST can be run in 3 different speed modes :
	i)  Fast mode (takes about 690 ms)
	ii) Medium mode (takes about 2930 ms)
	iii) Slow mode (takes about 7500 ms)

To run POST, firmware file with name "83xx_post_fw.bin" should be present under
/lib/firmware directory. load_fw_file module parameter is used to specify
POST operation and its speed mode.
load_fw_file = 2 : Fast mode
load_fw_file = 3 : Medium mode
load_fw_file = 4 : Slow mode

o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed
  to have a bandwidth of at least this value.
  max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth
  of up to this value.

o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced
  which takes 4 arguments:
  netdev, VF number, min_tx_rate, max_tx_rate

o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler.

o Drivers that currently implement ndo_set_vf_tx_rate should now call
  ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth
  greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet
  implemented by driver.

o If user enters only one of either min_tx_rate or max_tx_rate, then,
  userland should read back the other value from driver and set both
  for IFLA_VF_RATE.
  Drivers that have not yet implemented IFLA_VF_RATE should always
  return min_tx_rate as 0 when read from ip tool.

o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then
  IFLA_VF_RATE should override.

o Idea is to have consistent display of rate values to user.

o Usage example: -

  ./ip link set p4p1 vf 0 rate 900

  ./ip link show p4p1
