process to determine the current timestamp configuration. In order to
implement this, store a copy of the timestamp configuration. In
addition, we can remove the 'int cmd' parameter as the new set_ts_config
function doesn't use it. I also fixed a typo in the function

The ixgbe driver allocates pages for its receive rings. It currently
uses 512 pages, regardless of page size. During receive handling it
adds the unused part of the page back into the rx ring, avoiding the
need for a new allocation.

On a ppc64 box with 64 threads and 64kB pages, we end up with
512 entries * 64 rx queues * 64kB = 2GB memory used. Even more of a
concern is that we use up 2GB of IOMMU space in order to map all this
memory.

The driver makes a number of decisions based on if PAGE_SIZE is less
than 8kB, so use this as the breakpoint and only allocate 128 entries
on 8kB or larger page sizes.

ixgbe_napi_disable_all calls napi_disable on each queue, however the busy
polling code introduced a local_bh_disable()d context around the napi_disable.
The original author did not realize that napi_disable might sleep, which would
cause a sleep while atomic BUG. In addition, on a single processor system, the
ixgbe_qv_lock_napi loop shouldn't have to mdelay. This patch adds an
ixgbe_qv_disable along with a new IXGBE_QV_STATE_DISABLED bit, which it uses to
indicate to the poll and napi routines that the q_vector has been disabled. Now
the ixgbe_napi_disable_all function will wait until all pending work has been
finished and prevent any future work from being started.

This patch fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This is caused because ixgbe_ptp_stop did not check to actually
ensure PTP was running first. The new implementation introduces a state in the
&adapter->state field which is used to indicate that PTP is running. (This
replaces the IXGBE_FLAG2_PTP_ENABLED field). This state will use the atomic
set_bit, test_bit, and test_and_clear_bit functions. ixgbe_ptp_stop will check
to ensure that PTP was enabled, (and if not, it will not attempt to do any
cleanup work from ixgbe_ptp_init). This resolves the lockdep annotation warning

Instead of adjusting the FCoE and Flow director limits based on the number
of CPUs we can define them much sooner.  This allows the user to come
through later and adjust them once we have updated the code to support the
set_channels ethtool operation.

I am still allowing for FCoE and RSS queues to be separated if the number
queues is less than the number of CPUs.  This essentially treats the two
groupings like they are two separate traffic classes.

In addition I am changing the initialization to use the MAX_TX/RX_QUEUES
defines instead of trying to compute the value as it will be possible in
upcoming patches for the user to request the maximum number of queues.

I have also updated things so that the upper limit on queues is exactly 63
instead of allowing it to go up to 64.  The reason for this change is to
address the fact thqt the driver only supports up to 63 queue vectors since
the hardware supports 64 MSI-X vectors, but one must be reserved for "other"
causes.

This change is meant to inline the Rx PTP descriptor handling.  The main
motivation is to avoid unnecessary jumps into function calls that we then
immediately exit because we are not performing timestamps.

The net result of this change is that ixgbe_ptp_rx_tstamp drops from .5% CPU
utilization in my performance runs to 0%, and the only value tested is the Rx
descriptor which should already be warm in the cache if not stored in a
register.

This patch copies the igb implementation of Tx timestamps, which uses a work
item to poll for the Tx timestamp. In addition it adds a timeout value of 15
seconds, after which it will stop polling.

This is necessary due to an issue with the descriptor being marked done before
the Tx timestamp event has occurred. These two events don't correlate, so using
the done bit on the descriptor as indication that the timestamp must already
have been taken leads to potentially dropped Tx timestamps (especially under
heavy packet load)

This patch removes ixgbe_ptp_match, and the corresponding packet filtering from
ixgbe driver. This code was previously causing some issues within the hotpath of
the driver. However the code also provided a check against possible frozen Rx
timestamp due to dropped packets when the Rx ring is full. This patch provides a
replacement solution based on the watchdog.

To this end, whenever a packet consumes the Rx timestamp it stores the jiffy
value in the rx_ring structure. Watchdog updates its own jiffy timer whenever
there is no valid timestamp in the registers.

If watchdog detects a valid timestamp in the registers, (meaning that no Rx
packet has consumed it yet) it will check which time is most recent, the last
time in the watchdog, or any time in the rx_rings. If the most recent "event"
was more than 5seconds ago, it will flush the Rx timestamp and print a warning
message to the syslog.

This change is meant to improve the efficiency of the Tx flags in ixgbe by
aligning them with the values that will later be written into either the
cmd_type or olinfo.  By doing this we are able to reduce most of these
functions to either just a simple shift followed by an or in the case of
cmd_type, or an and followed by an or in the case of olinfo.

To do this I also needed to change the logic and/or drop some flags.  I
dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since
the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO.
I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a
clear point for what the flag is meant to do.  Finally the
IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data
for that flag in the skb.  Instead we can just check the bitflag in the skb.

In order to avoid type conversion errors I also adjusted the locations
where we were switching between CPU and little endian.

This patch modifies when and where PTP registers and data are set. Previously
a work-around was used inside cyclecounter_start in order to reset some of the
time registers. This patch creates a new ixgbe_ptp_reset specifically for this
purpose. The cyclecounter configuration has trimmed down to only modify what
is necessary. Due to hardware conditions after probe and before open, PTP init
has now moved into the ixgbe_open call. This allows the ptp device name in the
sysfs to be the ethernet device name instead of the MAC address.

The cyclecounter check flag is renamed to PTP_ENABLED and is used to prevent
PTP init from happening when PTP has not been enabled.
