Hello Olivier,

While continuing rebase of my work to the current HEAD I encountered
another problem regarding the PCIe NIC this time.

I'm using Realtek card and starting from this revision Rx buffers cannot be
allocated for my device.
Please check out the message below:

-----------------------------------------------------------------------------------
root@:~ # dhclient re0
re0: no memory for RX buffers
re0: no memory for RX buffers
DHCPREQUEST on re0 to 255.255.255.255 port 67
Aug  5 20:18:52  dhclient[898]: send_packet: Network is down
-----------------------------------------------------------------------------------

Best regards
