[lwip-devel] [bug #28106] duplicate acknowledge for fast retransmit could have not null length

[Simon Goldschmidt]

Follow-up Comment #4, bug #28106 (project lwip):

The attached patch moves the empty-ACK-sending code from tcp_output() to a
new dedicated function (tcp_send_empty_ack) that is used from tcp_output.

To fix this bug, all 4 calls to tcp_ack_now() inside tcp_receive() have been
changed to call tcp_send_empty_ack() (the first might not be required).

Any comments before checking in?
