            Bug ID: 452975
           Summary: Support Interface Combinations on Physical interfaces
           Product: plasma-nm
           Version: master
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: jgrul...@redhat.com
          Reporter: rawat.ar...@protonmail.com
  Target Milestone: ---

SUMMARY
Currently, plasma-nm does not allow a network card to run in both AP and
managed modes. In order for an active connection to be shared, there must be a
second wifi interface available.

Some network cards are able to do both simultaneously, such as all recent intel
cards. This can be checked with iw phy | grep -A 2 "interface combinations" ,
which returns 

* #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 1, #{ P2P-device } <= 1,
                   total <= 3, #channels <= 2

with an intel ax210 card. Accordingly, plasma-nm should support configuring the
network card to run in both managed and AP. This has an obvious use case, as
well as an implementation in windows for precedent.

STEPS TO REPRODUCE
1. Connect to a network (must be on a device with one wifi card and no wwan,
usually a laptop)
2. Hotspot button disappears
3. Can't create hotspot

OBSERVED RESULT
The hotspot button disappears, and no hotspot can be created

EXPECTED RESULT
Dependent on the hardware capabilities, the current wifi connection can be
shared through a hotspot.
