ad6e82a534 iwlwifi: move check health code into iwl-rx.c
Remove check_plcp_health and check_ack_health ops methods, they are

cd017f25e3 iwlagn: fix scan tx antenna setting on 5Ghz band
Looks that we do not set correctly antennas when scanning
on 5Ghz band and when bluetooth is enabled, because
priv->cfg->scan_tx_antennas[band] is only defined for
IEEE80211_BAND_2GHZ.

To fix we check band before limiting antennas to first one.
This allow to remove hard coded cfg->scan_tx_antennas[band].

The current EEPROM reading code has some layout
assumptions that now turned out to be false with

However, for risk mitigation purposes, keep the

2295c66b68 iwlagn: new RXON processing for modern devices
In order to simplify the flow, and make new
enhancements easier, separate out the RXON
processing for modern AGN (5000 and newer)
from RXON processing for the older 3945 and
4965 devices. Avoid changing these old ones
to avoid regressions and move their code to
a new file (iwl-legacy.c). 4965 gets the
commit_rxon that used to be common for all
AGN devices, but with removed PAN support.

The new RXON processing is more central and
does more work in committing, so that it is
easier to follow.

To make it more evident what is split out
for legacy, split the necessary operations
for that into a new struct iwl_legacy_ops.
Those parts that still exist in the new AGN
code don't need to be parametrized.

Actually, this patch does not disable DC calib for init uCode. It just
prevent driver from saving and sending the DC calib results (from init
ucode) to runtime uCode. The driver still uses 0xffffffff in

6b5ce50142 iwlwifi: add iwl_nic_ops structure to iwl_ops
iwlwifi driver supports multiple devices. Since some device needs
special configuration we create a new iwl_nic_ops structure which is
configurable per device. Currently there is only one function pointer
inside this structure: additional_nic_config().

The iwl_nic_ops structure is added to the top level in struct iwl_ops,
making it easier to change per device. Duplication of the iwl_lib_ops
structure is no longer needed.

With this new ops the previous function pointer set_calib_version is
no longer needed since it is just a per device nic configuration.

As part of the code restructuring, a bug is addressed. Indication of
calib version to uCode is only needed for 6050 devices, however,
current implementation set calib version for all 6000 devices for
which DC calib is needed. To fix this, create iwl6050_ops for 6050
devices and only populate iwl_nic_ops in this structure.
