The network stack indicate packets should not be DCB
tagged by setting the priority to TC_PRIO_CONTROL. One
usage for this is lldp frames which are not suppossed

When in packet split mode, packet type is not recognized, and the packet is
larger than the header size, the 82599 overflows the packet into the data
area, but doesn't set the HDR_LEN field. We can safely assume the length
is the current header size. This fixes an obscure corner case that can be
triggered by non-ip packet headers or (more likely) by disabling the L2
packet recognition.

Everytime the iSCSI ring finishes setup or shutdown, we need to return
the SPQ (slow path queue) credit to the bnx2x driver. Without this step,
the SPQ will eventually be full causing iSCSI to fail. This can happen
after 3 or 4 MTU changes for example.
Add code to wait for these slow path commands to complete in the RX ring
and return the SPQ credit to bnx2x.

The SJA1000 command register is concurrently written in the rx-path to free
the receive buffer _and_ in the tx-path to start the transmission.
The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states:
"Between two commands at least one internal clock cycle is needed in
order to proceed. The internal clock is half of the external oscillator
frequency."
On SMP systems the current implementation leads to a write stall in the
tx-path, which can be solved by adding some general locking and some time
to settle the write_reg() operation for the command register.
Thanks to Klaus Hitschler for the original fix and detailed problem
description.
This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .

The SH SOHARD ARCNET cards are implemented using generic PLX Technology
PCI<->IOBus bridges. Subvendor and subdevice IDs were not specified,
causing the driver to attach to any such bridge and likely crash the
system by attempting to initialize an unrelated device.
Fix by specifying subvendor and subdevice according to the values found
in the PCI-ID Repository at http://pci-ids.ucw.cz/ .

Add enic ndo_{set|get}_vf_port ops to support setting/getting
port-profile for enic dynamic devices. Enic dynamic devices are just like
normal enic eth devices except dynamic enics require an extra configuration
step to assign a port-profile identifier to the interface before the
interface is useable. Once a port-profile is assigned, link comes up on the
interface and is ready for I/O. The port-profile is used to configure the
network port assigned to the interface. The network port configuration
includes VLAN membership, QoS policies, and port security settings typical
of a data center network.
A dynamic enic initially has a zero-mac address. Before a port-profile is
assigned, a valid non-zero unicast mac address should be assign to the
dynamic enic interface.

The member "clock" of struct "sja1000_platform_data" is documented as
"CAN bus oscillator frequency in Hz" but it's actually used as the CAN
clock frequency, which is half of it. To avoid further confusion, this
patch fixes it by renaming the member to "osc_freq". That way, also
non mainline users will notice the change. The platform code for the
relevant boards is updated accordingly. Furthermore, pre-defined
values are now used for the members "ocr" and "cdr".

dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in
dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and
net_device_ops respectively). This causes a spinlock recursion BUG. Fix this by
renaming these functions to *_unlocked for the atomic context, and make the
original functions locking wrappers for use in the non-atomic context.

The current link checking logic only works for one port, which is not correct
for swiches were multiple ports can have different link status. As a result
we would only check for link status on port 1 of the switch. Move the calls
to mii_check_media in r6040_timer which will be polling a single PHY chip
correctly and assume link is up for switches.

Based on original patch from Stanislaw Gruszka <sgruszka@redhat.com>.
Using netif_carrier_off() is better than updating all the ->trans_start
on all the tx queues.
netif_carrier_off() needs to be called after bnx2_disable_int_sync()
to guarantee no race conditions with the serdes timers that can
modify the carrier state.
If the chip or phy is reset, carrier will turn back on when we get the
link interrupt. If there is no reset, we need to turn carrier back on
in bnx2_netif_start(). Again, the phy_lock prevents race conditions with
the serdes timers.

IP checksum is based on 16-bit one's complement algorithm, so to deduce a
value from checksum is equal to add its complement.
Unfortunately, the Blackfin on-chip MAC checksum logic only works when the
IP packet has a header length of 20 bytes. This is true for most IPv4
packets, but not for IPv6 packets or IPv4 packets which use header options.
So only use the hardware checksum when appropriate.

The skb buffer isn't actually used until we finish transferring and pass
it up to higher layers, so only invalidate the range once before we start
receiving actual data. This also avoids the problem with data invalidating
on Blackfin systems -- there is no invalidate-only, just invalidate+flush.
So when running in writeback mode, there is the small (but not uncommon)
possibility of the flush overwriting valid DMA-ed data from the cache.
