The SS_LISTEN socket state is defined by both af_vsock.c and
vmci_transport.c. This is risky since the value could be changed in one
file and the other would be out of sync.
Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part
of enum socket_state (SS_CONNECTED, ...). This way

This path introduces a helper which can give a hint for whether or not
there's a work queued in the work list.

This patch tries to poll for new added tx buffer for a while at the
end of tx processing. The maximum time spent on polling were limited
through a module parameter. To avoid block rx, the loop will end it
there's new other works queued on vhost so in fact socket receive
queue is also be polled.

Hi all:
This series tries to add basic busy polling for vhost net. The idea is
simple: at the end of tx processing, busy polling for new tx added
descriptor and rx receive socket for a while. The maximum number of
time (in us) could be spent on busy polling was specified through
module parameter.
