netdev - Re: [PATCH 1/1] When timestamping is enabled, stmmac_tx_clean will call stmmac_get_tx_hwtstamp to get tx TS. It's possible that skb is NULL because there are other network frames that use several descriptors. So we must return immediately in stmmac_get_tx_hwtstamp if skb is NULL to avoid system crash.
