Re: [RTnet-developers] race condition in e1000_xmit_frame ?

[Frederik B. <fb...@tr...>]

By releasing the lock after the e1000_tx_queue command, my problem was
solved.

     e1000_tx_queue(adapter, tx_ring, tx_flags,
                    e1000_tx_map(adapter, tx_ring, skb, first,
                                 max_per_txd, nr_frags, mss),
                    skb->xmit_stamp);
     rtdm_lock_put_irqrestore(&tx_ring->tx_lock, context);

Hi Frederick,

I think you are right. This could be actually the source for a race
condition...
Even with the original Intel driver e1000-7.1.9 the code is clean.
Did you try to fix it? Did the driver run without issue?

Best regards

Mathias
