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

FW Internal Memory structure
The FW uses data structures on the chip internal memory to aggregate the
connections when TPA is enabled. The driver was clearing the wrong offsets
and therefore one function could cause another function to loose packets.

relevant memory for each function which is being loaded

- Making sure that each drop is accounted for in the driver statistics
- Clearing the FW statistics when driver is loaded to prevent
inconsistency with HW statistics
- Once error is detected (bnx2x_panic_dump), stop the statistics

the data) - Adding HW checksum error counter to the statistics
- Removing unused variable stats_ticks
- Using macros instead of magic numbers to indicate which statistics are

Following "mac80211: fix TX sequence numbers", if a packet
has the IEEE80211_TX_CTL_ASSIGN_SEQ assigned, a sequence number must be
supplied, either by hardware or software. AFAIK, no such hardware exists
for the p54, thus it must be done in software. With this patch, a connection
qith p54usb is stable, whereas the interface went off-line in 2-3 hours
without this change. Note that this code will have to be reworked for proper
sequence numbers on beacons. In addition, the sequence number has been placed
in the hardware state, not the vif state.

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.

the motivation for this is to handle locking rationally (in this case,
removing conditional locking) and generally clean up the code.

an inspection phase, followed by an optional commit phase. The commit phase
is the only portion that requires RTNL or makes changes to state, and is
only called when inspection finds something to change.

Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
it will broken upper layer handle for promisc and allmulti.
In addition, drivers can use their own hardware programming to make it.
So do not allow drivers to set IFF_* flags.
