Enable firmware-configured 2.5Gbps operation on Warpcore SFI and
BCM8727-family PHYs, accept SC connector modules, and preserve a requested
2.5G speed when a GPON module identifies itself as a 1G SFP. Add an opt-in
TX-fault mask indexed by hardware path and port for BCM578xx SFI ports.

Report media using the active PHY, current speed, duplex, and pause state.
Cache SFP compliance bytes to identify optics, invalidate the cache when
modules or port ownership change, and use existing backplane media types.
Recognize 10G ER during module classification. Handle SIOCGIFXMEDIA and
update the interface baud rate on link changes.

Correct the supported-capability mask for 1G SFPs and advertise only the
auto media setting accepted by the driver. Document the NVRAM prerequisites,
the TX-fault mask's scope, and the hardware-dependent support beyond the
reported BCM57810 configuration.

10178	I cannot understand this bitmask conditions. It looks to me that you are enforcing 1G capability to be enabled in cap_mask even for 2_5G. Why?
