I added printk() to see where/if those first packets get dropped in e1000e code. I followed those first packets to e1000_xmit_frame() and don't see anything obvious happening there, i.e. they are passed to the device as expected. If I find some time tomorrow, I will try and take a look at e1000_watchdog_task() and other functions that may perform asynchronous tasks.
