Subject: net: Add a 'do_not_pad" to NetClientState
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=935344bed6769d6bcb74c6d992818929a6ccb35b;p=qemu.git

net: Add a 'do_not_pad" to NetClientState

This adds a flag in NetClientState, so that a net client can tell
its peer that the packets do not need to be padded to the minimum
size of an Ethernet frame (60 bytes) before sending to it.
