The atl1 driver tries to determine the MAC address thusly:
- If an EEPROM exists, read the MAC address from EEPROM and
validate it.
- If an EEPROM doesn't exist, try to read a MAC address from
SPI flash.
- If that fails, try to read a MAC address directly from the
MAC Station Address register.
- If that fails, assign a random MAC address provided by the
kernel.
We now have a report of a system fitted with an EEPROM containing all
zeros where we expect the MAC address to be, and we currently handle
this as an error condition. Turns out, on this system the BIOS writes
a valid MAC address to the NIC's MAC Station Address register, but we
never try to read it because we return an error when we find the all-
zeros address in EEPROM.
This patch relaxes the error check and continues looking for a MAC
address even if it finds an illegal one in EEPROM.

Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.
This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

The ibm_newemac driver requires ether_crc to be defined. Apparently it is
possible to generate a .config without CONFIG_CRC32 set which causes the
following link errors if IBM_NEW_EMAC is selected:

Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.

A few general categories:
1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de
in the same order as the fctl defines:
A combined _has_a4 was also added to test when both FROMDS and TODS are set.
2) ieee80211_is_* is meant to test whether the frame control is of a certain
ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres
which also test a subset of the stype space.
When testing for a particular stype applicable only to one ftype, functions
like ieee80211_is_ack have been added. Note that the ftype is also being
checked in these helpers. They have been added for all mgmt and ctl stypes
in the same order as the STYPE defines.
3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a
pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl.
The intel wireless drivers had helpers that used this namespace, convert the
all to use the new helpers and remove the byteshifting as they were defined
in cpu-order rather than little-endian.

mac80211_hwsim is a Linux kernel module that can be used to simulate
arbitrary number of IEEE 802.11 radios for mac80211 on a single
device. It can be used to test most of the mac80211 functionality and
user space tools (e.g., hostapd and wpa_supplicant) in a way that
matches very closely with the normal case of using real WLAN
hardware. From the mac80211 view point, mac80211_hwsim is yet another
hardware driver, i.e., no changes to mac80211 are needed to use this
testing tool.

This patch enables ibss mode. It consists of two changes upon entering ibss
mode:
1. Removing the redundant line which clears the driver's station table.
This line creates a discrepancy between the driver and the FW's station
table. This prevented the generation of beacons.
2. Assigning a default value to priv's assoc_id. Normally given by an AP in
STA mode, this field is used as an indication for association. Being 0,
it prevented normal TX flow.
3. Remove a redundant ADD_STA command that cause uCode error.
4. Delay the set_mode until after the uCode is ready.
