Johannes Berg says:

====================
A small set of fixes for
 * queue selection in mesh/ocb
 * queue handling on interface stop
 * hwsim virtio device vs. some other virtio changes
 * dt-bindings email addresses
 * color collision memory allocation
 * a const variable in rtw88
 * shared SKB transmit in the ethernet format path
 * P2P client port authorization
====================
