MFC: r282941

sfxge: do not change CSUM_TSO when IFCAP_TSOx is changed

It is simply not required since the kernel checks corresponding
IFCAP_TSOx capability and CSUM_TSO in hw-assisted offloads.
Note that CSUM_TSO is two bits (CSUM_IP_TSO|CSUM_IP6_TSO) and both bits
are set in IPv4 and IPv6 mbufs.

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

- Also while at it, use __FBSDID.

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.
