The driver will crash when the chip has been initialized by EFI before
tg3_init_one().  In this case, the driver will call tg3_chip_reset()
before allocating consistent memory.

The bug is fixed by checking for tp->hw_status before accessing it
during tg3_chip_reset().

If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than
B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast
messages.  This is because the __b44_set_mac_addr call sets the zeroth CAM
entry to the MAC address of the device, and then the loop at line 1722
proceeds to overwrite it unless the value of i is set by the __b44_load_mcast
call.  However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set
to zero.

Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC
address.

This patch addresses the following issues with the pxa2xx FIr driver:

1. increment overrun error counter and not frame error counter on ICSR1_ROR bit set in ICSR1.
2. drop frames reported with the frame error from the IC.
3. when resetting the receiver and preparing it for the next DMA in pxa_irda_fir_irq() actually clear the Rx FIFO. See description in Table 11-2 in PXA270 Developer's Manual of the RXE bit.

Correction added in version 2: clearing the IC Rx FIFO also has to be done in pxa_irda_fir_dma_tx_irq()

Some atl1 boards get their MAC address written directly to the register
by the BIOS during POST, rather than storing it in EEPROM that's
accessible to the driver.  If the MAC register on one of these boards
is changed and then the module is unloaded, the permanent MAC address
will be forgotten until the box is rebooted.  We should save the
permanent address during removal if we've been messing with it.

In this driver, the default ethernet address is first set by by calling
eth_port_uc_addr_get() which reads the relevant registers of the
corresponding port as initially set by firmware. However that function
used the port_num field accessed through the private area of net_dev
before it was set.

The result was that one board I have ended up with the unicast address
set to 00:00:00:00:00:00 (only port 1 is connected on this board). The
problem appeared after commit 84dd619e.

This patch fixes the bug by setting mp->port_num prior to calling
eth_port_uc_get_addr().

On most tg3 chips, the memory enable bit in the PCI command register
gets cleared during chip reset and must be restored before accessing
PCI registers using memory cycles.  The chip does not generate
interrupt during chip reset, but the irq handler can still be called
because of irq sharing or irqpoll.  Reading a register in the irq
handler can cause a master abort in this scenario and may result in a
crash on some architectures.

Use the TG3_FLAG_CHIP_RESETTING flag to tell the irq handler to exit
without touching any registers.  The checking of the flag is in the
"slow" path of the irq handler and will not affect normal performance.
The msi handler is not shared and therefore does not require checking
the flag.
