netdev: fix concurrency issues with multiple sockets #642

Closed scottfeldman closed 5 months ago

scottfeldman commented 5 months ago

The wifinina driver was not handling multiple concurrent sockets correctly. This PR fixes the wifinina driver and adds an example/net/snake test for testing multiple concurrent sockets. The wioterminal driver (rtl8270dn) needed no changes to pass the snake test.

I tested these changes and they appear to be working as expected.

Rebased to squash the last 3 commits together, then merged to dev. Thanks for the fixes @scottfeldman
