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.

With the patch applied the number of instruction events is 1% less and
number of mispredicted branch events is 5% less under multistream TCP
traffic load close to line rate.

Remove trailing whitespaces and tabs.
Enclose value in return statements in parentheses.
Use tabs after #define.
Do not skip comparison with 0/NULL in boolean expressions.

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.

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.

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.
