Eyal Perry 892311f66f ethtool: Support for configurable RSS hash function
This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

Anish Bhatt 587ddfe2d2 cxgb4i : Remove duplicated CLIP handling code
cxgb4 already handles CLIP updates from a previous changeset for iw_cxgb4,
there is no need to have this functionality in cxgb4i. Remove duplicated code

Hariprasad Shenai 22c0b963d7 cxgb4: Fix FW flash logic using ethtool
Use t4_fw_upgrade instead of t4_load_fw to write firmware into FLASH, since
t4_load_fw doesn't co-ordinate with the firmware and the adapter can get hosed
enough to require a power cycle of the system.

Hariprasad Shenai 8203b509c5 cxgb4: Wait for device to get ready before reading any register
Call t4_wait_dev_ready() before attempting to read the PL_WHOAMI register
(to determine which function we have been attached to). This prevents us from
failing on that read if it comes right after a RESET.

Hariprasad Shenai 897d55df3c cxgb4vf: Add 40G support for cxgb4vf driver
Add 40G support for cxgb4vf driver. ethtool speed values are just numbers of
megabits and there is no SPEED_40000 in ethtool speed values. To be consistent,
use integer constants directly for all speeds.

Use is_x_10g_port()("is 10Gb/s or higher") in cfg_queues() instead of
is_10g_port() ("is exactly 10Gb/s"). Else we will end up using a single
"Queue Set" on 40Gb/s adapters.
