[Qemu-devel] [PULL 1/2] ui/vnc: set TCP_NODELAY

[Gerd Hoffmann]

From: Peter Lieven <pl@kamp.de>

we currently have the Nagle algorithm enabled for all outgoing VNC updates.
This may delay sensitive updates as mouse movements or typing in the console.
As we currently prepare all data in a buffer and then send as much as we can
disabling the Nagle algorithm should not cause big trouble. Well established
VNC servers like TightVNC set TCP_NODELAY as well.
A regular framebuffer update request generates exactly one framebuffer update
which should be pushed out as fast as possible.

[Gerd Hoffmann]

  Hi,

Starting to flush queues after the 2.2 release, starting with two little
vnc fixes.  Well, keymap is strictly speaking not vnc, but vnc is the
major user of keymap support, so I sticked it in here.

please pull,
  Gerd
