DCB support when multiple traffic classes are actually

This enables multiple {Tx|Rx} rings per traffic class while in DCB
mode. In order to get this working as expected the tc_to_tx net
device mapping is configured as well as the prio_tc_map.
skb priorities are mapped across a range of queue pairs to get
a distribution per traffic class. The maximum number of
queue pairs used while in DCB mode is capped at 64. The hardware
max is actually 128 queues but 64 is sufficient for now and
allocating more seemed a bit excessive. It is easy enough to
increase the cap later if need be.
To get the 802.1Q priority tags inserted correctly ixgbe was
previously using the skb queue_mapping field to directly set
the 802.1Q priority. This no longer works because we have removed
the 1:1 mapping between queues and traffic class. Each ring
is aligned with an 802.1Qaz traffic class so here we add an
extra field to the ring struct to identify the 802.1Q traffic
class. This uses an extra byte of the ixgbe_ring struct
fortunately there was a 2byte hole,
struct ixgbe_ring {
void * desc; /* 0 8 */
struct device * dev; /* 8 8 */
struct net_device * netdev; /* 16 8 */
union {
struct ixgbe_tx_buffer * tx_buffer_info; /* 8 */
struct ixgbe_rx_buffer * rx_buffer_info; /* 8 */
}; /* 24 8 */
long unsigned int state; /* 32 8 */
u8 atr_sample_rate; /* 40 1 */
u8 atr_count; /* 41 1 */
u16 count; /* 42 2 */
u16 rx_buf_len; /* 44 2 */
u16 next_to_use; /* 46 2 */
u16 next_to_clean; /* 48 2 */
u8 queue_index; /* 50 1 */
u8 reg_idx; /* 51 1 */
u16 work_limit; /* 52 2 */
/* XXX 2 bytes hole, try to pack */
u8 * tail; /* 56 8 */
/* --- cacheline 1 boundary (64 bytes) --- */
Now we can set the VLAN priority directly and it will be
correct. User space can indicate the 802.1Qaz priority
using the SO_PRIORITY setsocket() option and QOS layer will
steer the skb to the correct rings. Additionally using
the multiq qdisc with a queue_mapping action works as
well.

This implements dcbnl get and set capabilities ops. The
devices supported by ixgbe can be configured to run in
IEEE or CEE modes but not both.
With the DCBX set capabilities bit we add an explicit
signal that must be used to toggle between these modes.
This patch adds logic to fail the CEE command set_hw_all()
which programs the device with a CEE configuration if
the CEE caps bit is not set. Similarly, IEEE set
commands will fail if the IEEE caps bit is not set. We
allow most CEE config set commands to occur because they
do not touch the hardware until set_hw_all() is called.
The one exception to the above is the {set|get}app routines.
These must always be protected by caps bits to ensure
side effects do not corrupt the current configured mode.
By requiring the caps bit to be set correctly we can
maintain a consistent configuration in the hardware
for CEE or IEEE modes and prevent partial hardware
configurations that may occur if user space does
not send a complete IEEE or CEE configurations.
It is expected that user space will signal a DCBX mode
before programming device.

The X540 devices grabs semaphores differently than 82599 and 82598
devices do. They do however also grab them in allot of the same
functions. So I'm adding a new MAC operation function pointer to
allow us to use the correct function based on our MAC type. I'm also
changing all the semaphore calls to use this new function pointer.

The X540 PHY reset pointer isn't currently used which is a good thing as it
wouldn't work as implemented. On top of that the X540 firmware is written
with the assumption that is does not need to be reset for proper
initialization so it's not needed. I'm just assigning the pointer at NULL
as the current implementation is rather misleading.

the link had previously gone down since the last time the LINKS
register was read. This does not accurately reflect the function of
the check link call, which should be to return the CURRENT link

reset when DCB bandwidth configurations were changed. This can
now be done dynamically without a reset so the bit is no longer
needed. The only remaining operations that force a device reset
are DCB enable/disable and FCoE application priority changes.
