We know that RX_BUF_SIZE is assigned the value 1522 in

I'd like to know that is it ok if I write a patch to change the value
from 1522 to IEEE80211_MAX_FRAME_LEN(2352)?
If the answer is negative, Would you please tell me why?
I got an bug report about this, During a pxe guest installation, after
loading kernel, if sending jumbo frame packets, say
'ping -i0.5 -M do -s 8972 $GUEST_IP' from host, The guest installation
will hang, So I want to increase the rx buffer
size of virtio-net to avoid this overflow. That's why I ask this question.
This happens *after* booting the kernel?
If so, then iPXE is no longer executing. Any problem would be in the
kernel's virtio drivers.
