[Qemu-devel] [PATCH v2 0/4] e1000: link auto-negotiation fixes

[Gabriel L. Somlo]

New in v2:

  - checking for E1000_FLAG_AUTONEG in s->compat_flags when deciding
    whether to run the auto-negotiation timer vs. simply forcing the
    link up during e1000_set_link_status()

  - grouped E1000_FLAG_AUTONEG check in s->compat_flags tighter with
    the rest of the auto-negotiation checks in the two other locations
    they appear in the source code (hopefully improving clarity).

  - added patch to move the auto-negotiation timer function past set_ics()
    to avoid the need for a forward declaration.


This series contains a few fixes and improvements in the emulation
of link auto-negotiation:

  - use auto-negotiation when the link is bounced externally (e.g. via
    set_link <foo> down/up on the qemu monitor command line).

  - allow mii_tool on linux access to all the phy registers and flags
    it requires in order to report a successfully auto-negotiated link.

  - inject LSC interrupt upon successful link auto-negotiation (required
    by stock OS X e1000 driver).

Gabriel L. Somlo (4):
  e1000: emulate auto-negotiation during external link status change
  e1000: improve auto-negotiation reporting via mii-tool
  e1000: move e1000_autoneg_timer() to after set_ics()
  e1000: signal guest on successful link auto-negotiation
