[PATCH 0/2] Retry SYNs for inbound connections

[Yumei Huang <yuhuang@redhat.com>]

When a client connects, SYN would be sent to guest only once. If the 
guest is not connected or ready at that time, the connection will be
reset in 10s. These patches introduce the SYN retry mechanism similar
to retransmits.

Tested two scenarios:

1) A guest is connected in a few seconds, the client connects
to the guest successfully.

2) No guest connects at all, the client gets "Connection reset" in 80s.

Also ran the testsuits, no regression issue introduced.

Yumei Huang (2):
  tcp: Rename "retrans" of struct tcp_tap_conn and tcp_tap_transfer
  tcp: Resend SYN for inbound connections
