========================================
The SFC EFX PMD (**librte_pmd_sfc_efx**) provides poll mode driver support
for **Solarflare SFN7xxx and SFN8xxx** family of 10/40 Gbps adapters.
for **Solarflare SFN7xxx and SFN8xxx** family of 10/40 Gbps adapters and
**Solarflare XtremeScale X2xxx** family of 10/25/40/50/100 Gbps adapters.
SFC EFX PMD has support for the latest Linux and FreeBSD operating systems.

Tunnels support

NVGRE, VXLAN and GENEVE tunnels are supported on SFN8xxx family adapters

NVGRE, VXLAN and GENEVE tunnels are supported on SFN8xxx and X2xxx family
adapters with full-feature firmware variant running.
**sfboot** should be used to configure NIC to run full-feature firmware variant.
See Solarflare Server Adapter User's Guide for details.
SFN8xxx family adapters provide either inner or outer packet classes.
SFN8xxx and X2xxx family adapters provide either inner or outer packet classes.
If adapter firmware advertises support for tunnels then the PMD
configures the hardware to report inner classes, and outer classes are
not reported in received packets.
However, for VXLAN and GENEVE tunnels the PMD does report UDP as the
outer layer 4 packet type.
SFN8xxx family adapters report GENEVE packets as VXLAN.
SFN8xxx and X2xxx family adapters report GENEVE packets as VXLAN.
If UDP ports are configured for only one tunnel type then it is safe to
treat VXLAN packet type indication as the corresponding UDP tunnel type.
