[PATCH v2 00/11] lwIP sandbox tests

[Jerome Forissier]

** Note ** I am resending essentially to have Simon's R-b tag on all
commits in patchwork; no review requested. Sorry for the noise.

This series enables most of the driver model tests for network features
with NET_LWIP (test/dm/eth.c and test/dm/dsa.c).
- Patches 1-4 fix a few bugs (device selection) and add missing features
(sandbox timer, restart support) to NET_LWIP
- Patch 5 decouples the sandbox ethernet driver from NET
- Patch 6 adds missing static IP addresses that NET_LWIP needs
- Patches 7 and 8 update the tests to use a common interface to send
  ICMP packets (do_ping(...) instead of net_loop(PING))
- Patch 9 enables DM_DSA and the associated tests with NET_LWIP
- Patch 10 adds a sandbox64 configuration with NET_LWIP=y
- Patch 11 adds that configuration to the CI

Changes in v2:
- Rebase on master and therefore drop patch "net: lwip: do_ping() should
  return CMD_RET_FAILURE when no device" which is merged already
- Apply Simon's Reviewed-by: tag to each and every commit
