Summary

In the Linux kernel, the following vulnerability has been resolved:

ice: Don't tx before switchdev is fully configured

There is possibility that ice_eswitch_port_start_xmit might be called while some resources are still not allocated which might cause NULL pointer dereference. Fix this by checking if switchdev configuration was finished.
