If a\ndescriptor slot was reused while it still held a stale true from\na previous SKB (possible when tx_spb_ring_full() underreported\nfullness), bcmasp_tx_reclaim() would see last == true mid-SKB and\ncall dev_consume_skb_any() prematurely, freeing the sk_buff while\nits remaining fragments were still in flight.\n\nUnconditionally clear txcb-\u003elast before the conditional set so every\ndescriptor slot starts from a known false state regardless of what a\nprior transmission left behind.",
