This change is meant to address several race issues that become possible
because next_to_watch could possibly be set to a value that shows that the
descriptor is done when it is not.  In order to correct that we instead make
next_to_watch a pointer that is set to NULL during cleanup, and set to the
eop_desc after the descriptor rings have been written.

To enforce proper ordering the next_to_watch pointer is not set until after
a wmb writing the values to the last descriptor in a transmit.  In order to
guarantee that the descriptor is not read until after the eop_desc we use the
read_barrier_depends which is only really necessary on the alpha architecture.

The current firmware header parsing is complicated due to interpreting it as a
u32 array and accessing header members via array offsets. Add tg3_firmware_hdr
structure to access the firmware fields instead of hardcoding offsets. The same
header format will be used for individual firmware fragments in the 57766.

The fw_hdr and tg3 structures have all the information required for
loading the fw. Remove the redundant fw_info structure and pass fw_hdr
instead.

tg3 used the fw_needed member loosely as a synonym for firmware TSO. Now
that the 57766 needs firmware download support, fw_needed can no longer be
used like this. This patch creates a new FW_TSO flag and changes the
code to use it.

Also rearrange all the TSO flags together in the enum.

This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and resume functions.
Serveral variables allocted dynamically were removed and replaced by stack variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.

This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

allocates memory using kvasprintf(), but this memory isn't freed if
the underlying device isn't registered properly, because kobject_cleanup()
is not called in that case. This can happen (and actually is happening on
our machines) if phy_device_register(), called by mdiobus_scan(), fails.

I'm not sure why, but the hlist for each entry iterators were conceived

        list_for_each_entry(pos, head, member)

The hlist ones were greedy and wanted an extra parameter:

        hlist_for_each_entry(tpos, pos, head, member)

Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.

Besides the semantic patch, there was some manual work required:

 - Fix up the actual hlist iterators in linux/list.h
 - Fix up the declaration of other iterators based on the hlist ones.
 - A very small amount of places were using the 'node' parameter, this
 was modified to use 'obj->member' instead.
 - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
 properly, so those had to be fixed up manually.

The semantic patch which is mostly the work of Peter Senna Tschudin is here:

For SD8688, FUNC_INIT command is queued before fw_ready flag is
set. This causes the following crash as lbs_thread blocks any
command if fw_ready is not set.

Fix it by setting fw_ready flag prior to queuing FUNC_INIT command.

If CONFIG_MAC80211_MESH is not set, cfg80211 will now allow advertising
interface combinations with NL80211_IFTYPE_MESH_POINT present.
Add appropriate ifdefs to avoid running into errors.

Maximum delay for waking up card is 50 ms. Because of typo in
counter, this delay goes to 500ms. This patch fixes the bug.

On many different chips, important aspects of the MAC state are not
fully cleared by a warm reset. This can show up as tx/rx hangs, those
annoying "DMA failed to stop in 10 ms..." messages or other quirks.

On AR933x, the chip can occasionally get stuck in a way that only a
driver unload/reload or a reboot would bring it back to life.

With this patch, a full reset is issued when bringing the chip out of
FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down
properly. This makes the DMA related error messages disappear completely
in my tests on AR933x, and the chip does not get stuck anymore.
