Yes, this commit is in stable tree:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/net/hyperv?id=99d3016de4f2a29635f5382b0e9bd0e5f2151487
	hyperv: Change the receive buffer size for legacy hosts

I will ask the maintainer, see if it will be in next 3.14 update as well.

Thanks,
