Title:
Unable to use Multicast with CDC_NCM driver
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am not able to send multicast in the 5.4.0-39 kernel. It appears
that this was previously triaged in 2018 but a comment in that same
bug report indicates that it could not be compiled for 5.x kernel
