Hot swap of  SFPs 10G/1G current is not support on Intel x553 controller with dpdk 21.11.3 

CPU  Intel(R) Atom(TM) CPU C3558R @ 2.40GHz

x553 ports bond to dpdk inserted with 10G and 1G SFPs

Same experiment with Linux ixgbe kernel driver and on hotswap on SFPs both link and speed were correctly reported. Logs below:

I saw some patches in the archives posted in 2021 which did not make it to the upstream release that support these features by Stephen.

Is there a plan to support this feature dpdk like linux kernel ixgbe driver ?

Thanks,
