i350 driver and hot swap of sfp modules

Dear community, 

 

i have eposted my question allready here: 
community.intel.com/t5/Ethernet-Products/I350-support-hot-swap-of-sfp-module/m-p/1483988

 

My questions in short: 
The i350 manual says "3.4.1.1 SDP usage for SFP connectivity
When an SFP module is connected to the SerDes interface, some of the SFP signals may be connected to SDPs."

The driver "https://sourceforge.net/projects/e1000/" seems to not support hot swapping of sfp modules -> if no sfp is inserted at probe time, the port is not work.

IMHO this is a general driver issue and not a special problem due to our custom board. 
I had a detailed look at the driver code and some internal data structures like phy callbacks are configured at probe time, which is not compatible with a sfp configuration. In a sfp configuration the phy can change at runtime. 

Does any reference exists which shows how the driver should be adopted to work properly with sfps regarding the sdps and reconfiguration if a sfp is attached  ? 


Thanks in advance
