lwIP | TI TMS570LC4357: DHCP setup failing despite correct host setup. (#22)

[Armaan Chowfin (@ar-in0)]

Issue created by Armaan Chowfin: https://gitlab.rtems.org/rtems/pkg/rtems-lwip/-/work_items/22



## Summary

After providing PHY clock and correcting lc4357 pinmux, autonegotiation in start_networking() succeeds, but dhcp times out waiting for a response. In addition, MAC status dump shows no tx frames were sent out (TXGOOD = 0)

## Steps to reproduce

On ubuntu host, ethernet over a usb-c adapter:

```bash
# make adapter a dnsmasq dhcp server
nmcli con add type ethernet ifname enxdc045a7f5ce2 con-name board-share ipv4.method shared

nmcli con up board-share

# listen for dhcp discover reqs on host
sudo tcpdump -i enxdc045a7f5ce2 -e -vv port 67 or port 68
```
