The tg3 driver is written so that VLAN tagged packets can be accepted,
even if CONFIG_VLAN_8021Q or CONFIG_VLAN_8021Q_MODULE is not defined.
(Think raw interfaces.) If the device has ASF support enabled, the
firmware requires the driver to enable VLAN tag stripping. If VLAN
tagging is not explicitly supported by the kernel and ASF is enabled,
the driver will have to reinject the VLAN tag back into the packet
stream.

On a PCIX bus, the 5701 has a bug which requires the driver to double
copy all rx packets. The rx code uses the rx_offset device member as a
flag to determine if this workaround should take effect. The following
patch will modify the rx_offset member such that this test will become
less clear.
The patch starts by integrating the workaround check into the packet
length check. It rounds out the implementation by relaxing the
workaround restrictions if the platform has efficient unaligned
accesses.

If a packet has the skb_shared_tx->hardware flag set the device is
instructed to generate a TX timestamp and write it back to memory after
the frame is transmitted. During the clean_tx_ring operation the
timestamp will be extracted and copied into the skb_shared_hwtstamps
struct of the skb.
TX timestamping is enabled by setting the tx_type to something else
than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only
supported by eTSEC devices.

The device is configured to insert hardware timestamps into all

alingment bytes during the clean_rx_ring operation and copied into the

The driver attempts to select an IRQ for the NIC automatically by
testing which of the supported IRQs are available and then probing
each available IRQ with probe_irq_{on,off}(). There are obvious race
conditions here, besides which:
1. The test for availability is done by passing a NULL handler, which
now always returns -EINVAL, thus the device cannot be opened:
<http://bugs.debian.org/566522>
2. probe_irq_off() will report only the first ISA IRQ handled,
potentially leading to a false negative.
There was another bug that meant it ignored all error codes from
request_irq() except -EBUSY, so it would 'succeed' despite this
(possibly causing conflicts with other ISA devices). This was fixed
by ab08999d60 'WARNING: some
request_irq() failures ignored in el2_open()', which exposed bug 1.
This patch:
1. Replaces the use of probe_irq_{on,off}() with a real interrupt handler
2. Adds a delay before checking the interrupt-seen flag
3. Disables interrupts on all failure paths
4. Distinguishes error codes from the second request_irq() call,
consistently with the first
Compile-tested only.

As reported in <https://bugzilla.kernel.org/show_bug.cgi?id=15355>, r6040_
multicast_list currently crashes. This is due a wrong maximum of multicast
entries. This patch fixes the following issues with multicast:
- number of maximum entries if off-by-one (4 instead of 3)
- the writing of the hash table index is not necessary and leads to invalid
values being written into the MCR1 register, so the MAC is simply put in a non
coherent state
- when we exceed the maximum number of mutlticast address, writing the
broadcast address should be done in registers MID_1{L,M,H} instead of
MID_O{L,M,H}, otherwise we would loose the adapter's MAC address
