[PATCH net 0/6] net: enetc: SR-IOV robustness and security fixes

[Wei Fang]

This series hardens the ENETC PF driver's SR-IOV implementation by
fixing multiple security and stability issues in the VF-to-PF mailbox
communication path, identified through code review.

Issues addressed:
  - Missing input validation for VF requests (security)
  - Race conditions in VF state management (stability)
  - Initialization ordering bugs (reliability)
  - Resource cleanup issues (memory safety)
  - Missing ratelimiting in error paths (DoS prevention)

All issues are theoretical (found through static analysis) but represent
real vulnerabilities exploitable by malicious guests or buggy VF drivers.

Wei Fang (6):
  net: enetc: validate VF primary MAC address before configuration
  net: enetc: fix race condition in VF MAC address configuration
  net: enetc: fix use-after-free in mailbox cleanup on interrupt race
  net: enetc: avoid VF->PF mailbox timeout during SR-IOV teardown
  net: enetc: fix initialization order to prevent use of uninitialized
    resources
  net: enetc: add ratelimiting to VF mailbox error messages
