Subject: [PATCH 0/4] thunderbolt: XDomain and NHI improvements

Hi,

This small series improves the "data" path handling when doing host-to-host
connections over TBT/USB4 cable. First patch delays setting nodename upon
first connect to allow the userspace to fill in host name. Rest of the
series deal with the NHI (TBT/USB4 host interface) HopID allocation so that
by dropping the E2E workaround which was never used, we can use DMA rings
starting from 1 to transfer data over the TBT/USB4 fabric.

Mika Westerberg (4):
  thunderbolt: Build initial XDomain property block upon first connect
  thunderbolt: No need to warn if NHI hop_count != 12 or hop_count != 32
  thunderbolt: NHI can use HopIDs 1-7
  thunderbolt: Get rid of E2E workaround
