[Bug 1454892] [NEW] [Hyper-V] hv_netvsc: Use the xmit_more skb flag to optimize signaling the host
Public bug reported:
hv_netvsc: Use the xmit_more skb flag to optimize signaling the host
Based on the information given to this driver (via the xmit_more skb flag),
we can defer signaling the host if more packets are on the way. This will help
make the host more efficient since it can potentially process a larger batch of
packets. Implement this optimization.
Upstream commit: https://git.kernel.org/cgit/linux/kernel/git/davem/net-
next.git/commit/?id=82fa3c776e5abba7ed6e4b4f4983d14731c37d6a
This commit may imply other commits previously requested, for example
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1452074
Requested for all typical Hyper-V targets: 15.10, 15.04, 14.10, 14.04,
14.04 HWE, 12.02, and 12.02 HWE
