ucode firmware may need to be released as experimental for testing or
debugging. released ucode filenames have the API version as the last
component.  experimental ucode files will have that component be "exp"
and the fw_version string reported by ethtool will also contain the
string EXP to clearly identify this ucode from released ucode.
EXP is short for EXPERIMENTAL since fw_version has a max lenght on 32.

Update outdated comments of iwl_set_rxon_channel() to reflect the
current signature. Also remove the unnecessary validation of the
channel. Those channel info are constructed in iwlwifi driver
and mac80211 will never modify the content of the struct. Also
everytime before this function is called the channel info has
been validated already (as a paranoid check).

When iwl_mac_config() is called by mac80211, the channel pointer
hw->conf->channel can potentially change, resulting in mismatch
band and channel number when configuring RXON command. To avoid
this situation, save the channel pointer in local variables
and validate the channel before using it. Note that priv->mutex
is locked during the whole function so the local variables are safe.

Same change is applied to iwl_mac_channel_switch() since basically
it copies code from iwl_mac_config().

Also removed an outdated comment in the flow.

A few cases in iwlwifi driver function ieee80211_frequency_to_channel()
is called to get channel number from center frequency. This is not needed
since the channel number is already saved in hw_value field of struct

Like other vendors, p54* devices have a checksum for
the EEPROM descriptor data. This patch enhances the
parser code to generate and verify the data fields,
before initializing the radio-chip on the card.

Note:
	If you have to bootstrap an alternative EEPROM image
	for your device and you don't know how to generate a
	valid crc ccitt checksum, you should take a look at:
	http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git

	The "checksum" utility loads a binary p54 EEPROM blob
	(use the -f switch, to skip the check) and applies
	the correct crc automatically.
