net: sfp: Add helper to return the SFP bus name

2024-08-23T12:04:34Z

Knowing the bus name is helpful when we want to expose the link topology to userspace, add a helper to return the SFP bus name. This call will always be made while holding the RTNL which ensures that the SFP driver won't unbind from the device. The returned pointer to the bus name will only be used while RTNL is held.

net: sfp: pass the phy_device when disconnecting an sfp module's PHY

2024-08-23T12:04:34Z

Pass the phy_device as a parameter to the sfp upstream .disconnect_phy operation. This is preparatory work to help track phy devices across a net_device's link.

net: sfp: Add more extended compliance codes

2024-06-28T09:48:23Z

SFF-8024 is used to define various constants re-used in several SFF SFP-related specifications. Add SFF-8024 extended compliance code definitions for CMIS compliant modules and use them in the next patch to determine the firmware flashing work.

net: revert partially applied PHY topology series

2024-05-14T01:35:02Z

The series is causing issues with PHY drivers built as modules. Since it was only partially applied and the merge window has opened let's revert and try again for v6.11.

Add support for parsing the rate select thresholds and switching of the RS0 and RS1 signals to the transceiver. This is complicated by various revisions of SFF-8472 and interaction of SFF-8431, SFF-8079 and INF-8074.
