sfxge(4): handle negative ticks difference correctly

ticks are signed int and if statistics is not updated for a long time
(more than INT_MAX ticks, but less than UINT_MAX) difference becomes
negative and less than hz for a long time.

Other option to repeat is simply load driver (which initializes
timestamps to 0) when ticks are negative.

sfxge: avoid usage of ifm_data

The driver uses ifm_data to save capabilities mask calculated during
initialization when supported phy modes are discovered.
The patch simply calculates it when either media or options are changed.

Check that port is started when MAC filter is set

The MAC filter set may be called without softc_lock held in the case of
SIOCADDMULTI and SIOCDELMULTI ioctls. The ioctl handler checks IFF_DRV_RUNNING
flag which implies port started, but it is not guaranteed to remain.
softc_lock shared lock can't be held in the case of these ioctls processing,
since it results in failure where kernel complains that non-sleepable
lock is held in sleeping thread.

Both problems are repeatable on LAG with LACP proto bring up.

sfxge: Fix if_baudrate reports

This field is supposed to be set to the interface bit rate, but for some
reason I thought it was denominated in kilobits. Multiply the values up
accordingly, taking care to saturate rather than overflow on 32-bit
architectures.

Add the sfxge(4) device driver, providing support for 10Gb Ethernet adapters
based on Solarflare SFC9000 family controllers. The driver supports jumbo
frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO),
Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side
Scaling (RSS) using MSI-X interrupts.
