Reports for two kinds of events are implemented, Malicious Driver
Detection (MDD) and Tx hang.
Patches 1, 2, 3: core improvements (checkpatch.pl, devlink extension)
Patches 3, 4, 5: ice devlink health infra + reporters
Mateusz did good job caring for this series, and hardening the code,
but he's on long vacation now :)
---
v3: - extracted devlink_fmsg_dump_skb(), and thus removed ugly copy-pasta
present in v2 (Jakub);
- tx hang reported is now called from service_task, to resolve calling
it from atomic (watchog) context - patch 4
v2: patch 3 (patch 4 in v3)
- added additional cast to long in ice_tx_hang_reporter_dump()
- removed size_mul() in devlink_fmsg_binary_pair_put() call
