* This series adds checks to avoid potential OOB access and infinite loop
   issues while processing rx/tx data.

* Tulip tx descriptors are capped at 128 to avoid infinite loop in
   tulip_xmit_list_update(), wrt Tulip kernel driver

* Update v3: add .can_receive routine
   -> https://lists.gnu.org/archive/html/qemu-devel/2020-02/msg06275.html

* Update v4: flush queued packets once they are received

* Update v5: fixed a typo in patch commit message

Thank you.
