Lower the min value of "tcp.delay_ack_msec" from 20ms to 1ms to be able to decrease the time before acks are sent.

The min value was set to 20ms in the because lower values caused performance issues. The tcp timer handling was changed during the latest TCP/IP stack uplift. The tcp timer tick resolution was fixed to 1ms and delay_ack_msec does not change the resolution anymore. There is no additional tcp timer handling with the change of delay_ack_msec value. So there should be no performance issues with allowing delay_ack_msec to be set to 1ms.
