The current driver code performs 512 DMA mappings of a bunch of
32-byte ring descriptor structures. This is silly, as they are
all in contiguous memory. This patch changes the code to
dma_map_coherent() each rx/tx ring as a whole.

Let's try to avoid some code duplication.
- cxgb2
The data are contiguous. Use plain memcpy.
- ixf1010/pm3393/vsc7326
The cast of &mac->stats to (u64 *) is not wonderful but it is not clear
if it is worth to add an ad-hoc union under the struct cmac_statistics.
vsc7326_reg.h suggests that more statistics could be available.

The current bcm43xx driver ignores any wireless-enable switches on mini-PCI
and mini-PCI-E cards. This patch implements a new routine to interrogate the
radio hardware enabled bit in the interface, logs the initial state and any
changes in the switch (if debugging enabled), activates the LED to show the
state, and changes the periodic work handler to provide 1 second response
to switch changes and to account for changes in the periodic work specs.

Instead of passing our own custom 32-bit addresses around and
translating them, this patch makes all our register address constants
absolute and removes the translation.
There are two ugly parts:
- fw_reg_addr() is needed to compute addresses of firmware registers, as this
is dynamic based upon firmware
- inc_addr() needs a small hack to handle byte vs word addressing
However, both of those are only small, and we don't use fw_regs a whole
lot anyway.
The bonuses here include simplicity and improved driver readability. Also, the
fact that registers are now referenced by 16-bit absolute addresses (as
opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has
been shaved off.
Includes some touchups and sparse fixes from Ulrich Kunitz.

The zd1211rw address space has confused me once too many times. This
patch introduces the following naming notation:
Memory space is split into segments (cr, fw, eeprom) and segments may
contain components (e.g. boot code inside eeprom). These names are
arbitrary and only for the description below:
x_START: Absolute address of segment start
(previously these were named such as CR_BASE_OFFSET, but they weren't
really offsets unless you were considering them as an offset to 0)
x_LEN: Segment length
x_y_LEN: Length of component y of segment x
x_y_OFFSET: Relative address of component y into segment x. The absolute
address for this component is (x_START + x_y_OFFSET)
I also renamed EEPROM registers to EEPROM data. These 'registers' can't
be written to using standard I/O and really represent predefined data
from the vendor.

The driver was still mis-calculating the number of bytes sent during
transmit, now the driver computes what appears to be exactly 100%
correct byte counts (not including CRC) when figuring out how many
bytes and frames were sent during the current transmit packet.
Since the driver sets the IP checksum insertion bit (IXSM in Status
field) in transmit context descriptors, it should clear the IP checksum
bits of any garbage so as not to confuse the hardware.

This fix attempts to solve a customer (IBM) reported issue with NAPI
enabled e1000 having bad performance when transmitting simultaneously
on four ports. The issue comes down to an interaction between NAPI,
hardware interrupt balancing, and the driver rescheduling poll on
the same processor. Try to fix by allowing the driver to re-enable
interrupts sooner instead of polling one more time, when there was
recently all the work completed in cleanup.

Quoth David:
"Jeff, please revert
It's wrong. We had a lengthy analysis of this piece of code
several months ago, and it is correct.
Consider, if we run the loop and we get an error
the following happens:
1) attempt of ifb_init_one(i) fails, therefore we should
not try to "ifb_free_one()" on "i" since it failed
2) the loop iteration first increments "i", then it
check for error
Therefore we must decrement "i" twice before the first
free during the cleanup. One to "undo" the for() loop
increment, and one to "skip" the ifb_init_one() case which
failed."

The b44 chip occasionally needs to be reset when ISTAT_ERRORS are
encountered. The reset sequence includes a PHY reset that will take many
seconds to complete and cause the link to go down and up. By skipping the
PHY reset, it will greatly reduce the interruption when ISTAT_ERRORS are
encountered.
Change the full_reset parameter to reset_kind parameter in b44_init_hw().
This will allow PHY reset to be skipped when ISTAT_ERRORS are encountered.
