should not be called yet. After the packet is really sent by

Parse and validate the sequence number and send the ACK synchronously
in the tcp_established() callback. No attempt is made to unify the
packet with any queued data (which isn't queued yet, but might be
someday).
Note that this requires that an accepted context clone over the
sequence numbers from the listening context (which received them
during the SYN).
(Note also that this exposes a bug in the current SYN handling:
there's only space for one set of sequence numbers on that listening
context, so if we get two SYNs before the round trip ACK arrives we'll
"accept" the wrong connection with garbage sequence numbers and both
connections will fail).

My previous race cleanup missed the fact that the memset would end up
clearing the IN_USE flag! So we were always allocating the same
struct net_tcp (which, because the typical use is to listen on one
socket and then transfer on an accepted socket, almost kinda worked
for a lot of stuff, making this hard to find).

Everytime the devices receives a frame with odd length it will
add an extra byte of padding to the reception buffer.
This was causing and issue when receiving frames above 64 bytes
length and with odd length.
This commit pops the extra padding byte everytime the received
frame has an odd length.
The equivalent fix is applied to the legacy driver.

When the driver receives or transmits a frames with a length
that is multiple of MAX_BUFFER_LENGTH the last block would be
read/sent twice to spi because a missed calculation on
num_remaining.
The issue is fixed by controling when the remaining bytes are
written/read into the spi device and by setting the spi command
on each spi write/read attempt.
The fix is applied to the legacy driver as well.
