inconsistent wget behavior

[Tim Harvey]

Greetings,

I've recently given wget/tcp a try and find the results inconsistent.

Transferring the same file 15 times in a row will eventually give me
an incomplete transfer with packet/byte count wrong but showing
'Transfer Successful'.

Here is current master on an imx8mp-venice-gw74xx board using IMX8MP
EQOS enet dev:
