[Qemu-devel] [PATCH V2] E1000 RX ring management fix

[Dmitry Fleytman]

Following patch fixes improper RX ring management E1000 code

Changes from version 1:
    1st patch changed so it drops check_rxov field because it is redundant and 
leads to race conditions
    See commit description for details

    2nd patch (live migration) dropped because corresponding field got deleted

Also I've made short experiment with an Intel adapter controlled by e1000e 
driver.
Indeed I saw no RX indication attempt when RX ring's RDH and RDT are equal.

Dmitry Fleytman (1):
  Drop check_rxov, always treat RX ring with RHD == RDT as empty
