Theory : though needless, it should not have hurt.
Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP

The device would not resume properly if it was shutdown before the system
was suspended. In such scenario where the netif_running state is 0,
bnx2_suspend() would not save the PCI state and so the memory enable bit
and bus master enable bit would be lost.
We fix this by always saving and restoring the PCI state in
bnx2_suspend() and bnx2_resume() regardless of netif_running() state.

During the transition to the ethtool_ops way of doing things, we supported
calling the device's ->do_ioctl method to allow unconverted drivers to
continue working. Those days are long behind us, all in-tree drivers
use the ethtool_ops way, and so we no longer need to support this.
The bonding driver is the biggest beneficiary of this; it no longer
needs to call ioctl() as a fallback if ethtool_ops aren't supported.

The FW command token is currently only updated on a command completion
event. This means that on command timeout, the same token will be
reused for new command, which results in a mess if the timed out
command *does* eventually complete.
This is the same change as the patch for mthca from Michael
S. Tsirkin <mst@dev.mellanox.co.il> that was just merged. It seems
sensible to avoid gratuitous differences in FW command processing
between mthca and mlx4.

Tina Yang <tina.yang@oracle.com> discovered an MSI related problem
when doing kdump. The problem is that the kexec kernel is booted
without going through system reset, and as a result, MSI may already
be enabled when tg3_init_one() is called. tg3_init_one() calls
pci_save_state() which will save the stale MSI state. Later on in
tg3_open(), we call pci_enable_msi() to reconfigure MSI on the chip
before we reset the chip. After chip reset, we call
pci_restore_state() which will put the stale MSI address/data back
onto the chip.
This is no longer a problem in the latest kernel because
pci_restore_state() has been changed to restore MSI state from
internal data structures which will guarantee restoring the proper
MSI state.
But I think we should still fix it. Our save and restore sequence
can still cause very subtle problems down the road. The fix is to
have our own functions save and restore precisely what we need. We
also change it to save and restore state inside tg3_chip_reset() in a
more straight forward way.
Thanks to Tina for helping to test and debug the problem.

The driver didn't allow an interface's MAC address to be modified if the
respective interface wasn't setup - a failing Hcall was the result. Thus
bonding wasn't usable. The fix moves the failing Hcall which was registering
a MAC address for the reception of BC packets in firmware from the port up
and down functions to the port resources setup functions. Additionally the
missing update of the last_rx member of the netdev structure was added.

The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay. So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII. This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.

The Vitesse 824x PHY doesn't allow an interrupt to be cleared if
the mask bit for that interrupt isn't set. This means that the PHY
Lib's order of handling interrupts (disable, then clear) breaks on this
PHY. However, clearing then disabling the interrupt opens up the code
for a silly race condition. So rather than change the PHY Lib, we change
the Vitesse driver so it always clears interrupts before disabling them.
Further, the ack function only clears the interrupt if interrupts are
enabled.
