Minor code improvements
Small changes to make the code a little bit more efficient and mostly
more readable:
- Using unified macros for EMAC_RD/WR which looks like normal REG_RD/WR
- Removing the NIG_WR since it did nothing and was only confusing
- On bnx2x_panic_dump, print only the used parts of the rings
- define parameters only on the branch they are needed and not at the
beginning of the function
- using NETIF_MSG_INTR and not private BNX2X_MSG_SP for debug prints

Pause settings
- 1G pause was not working due to missing write to the emac block
(TX_MODE_FLOW_EN)
- The flow control should use the negotiated result (after autoneg) so
we should save both the requested autoneg and the result
- The HW credits with flow control at 1G speed were not optimized and
caused low throughput
- It is recommended to turn off flow control if the MTU is bigger than
5000B due to internal buffers size

Link order with external PHY
When external PHY exists (second chip with the PHY to translate to
another physical medium) the link with the eternal PHY and the network
should be established before setting the link between the 5771x and the
PHY. This is the right order and it is important when using autoneg -
the link to the network should use the autoneg and the link between the
two chips should be forced to the network result.

Load/Unload under traffic
Few issues were found when loading and unloading under traffic:
- When receiving Tx interrupt call netif_wake_queue if the queue is
stopped but the state is open
- Check that interrupts are enabled before doing anything else on the
msix_fp_int function
- In nic_load, enable the interrupts only when needed and ready for it
- Function stop_leading returns status since it can fail
- Add 1ms delay when unloading the driver to validate that there are no
open transactions that already started by the FW
- Splitting the "has work" function into Tx and Rx so the same function
will be used on unload and interrupts
- Do not request for WoL if only resetting the device (save the time
that it takes the FW to set the link after reset)
- Fixing the device reset after iSCSI boot and before driver load - all
internal buffers must be cleared before the driver is loaded

It is wrong to destroy a bonding master from a context that uses the sysfs
of that bond. When last IPoIB slave is unenslaved from by writing to a
sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves)
the driver tries to destroy the bond. This is wrong and can lead to a
lockup or a crash. This fix lets the bonding master stay and relies on
the user to destroy the bonding master if necessary (i.e. before module
ib_ipoib is unloaded)
This patch affects only bonds of IPoIB slaves. Ethernet slaves stay
unaffected.

82573 EEPROMs have been shipped out with known issues. While most
people will never see the issues some people do and we know
how to address them. Warn the user if we find one of these
EEPROM issues.

The ndev_* printk's are too lenghty and we don't need to specify
the adapter/netdev struct at all, making this a lot more readable.

Set 64bits consistent DMA mask since it improves performance
in some cases. No need to check the return value since it is
not required for the driver to work.

This patch fixes the 'scheduling while atomic' errors introduced by
commit 12dac0756d ("tg3: adapt tg3 to
use reworked PCI PM code").
The first hunk of the patch removes an unnecessary
tg3_set_power_state() call. The chip will already be in the D0 state
either due to a chip reset or through a previous call to
tg3_set_power_state().
The second hunk of the patch moves the tg3_set_power_state() call
outside the critical section guarded by tg3_full_lock() and
tg3_full_unlock() functions. The power state of the device is and
should be outside the lock's domain and all other
tg3_set_power_state() calls support this.

This patch fixes unhandled interrupt when HW rfkill is on during
devices start up. The behavior changes, now open is successful even
when rfkill is on. This is to align with the situation when rfkill
is set on after opening.

This patch optimizes memory allocation. The cmd member of
iwl_tx_queue was allocated previously as a continuous block
of memory. This patch allocates separate memory chunks for each command
and maps/unmaps these chunks in the run time.
