[PATCH net-next 0/2 V2] Xen network: split event channels support
This series adds a new feature called split event channels. In the original implementation, only one event channel is setup between frontend and backend. This is not ideal as TX notification interferes with RX notification. Using dedicated event channels for TX and RX solves this issue. Changes since V1: * change subject lines of commits to be more specific * add parameter feature_split_event_channels for xen-netback * remove two dev_info Wei Liu (2): xen-netback: split event channels support for Xen backend driver xen-netfront: split event channels support for Xen frontend driver drivers/net/xen-netback/common.h | 13 ++- drivers/net/xen-netback/interface.c | 84 ++++++++++++++--- drivers/net/xen-netback/netback.c | 14 ++- drivers/net/xen-netback/xenbus.c | 40 ++++++-- drivers/net/xen-netfront.c | 173 +++++++++++++++++++++++++++++------ 5 files changed, 266 insertions(+), 58 deletions(-) -- 1.7.10.4

This change should then be synchronised into Linux''s include/xen/interface/io/netif.h copy as part of this series. Ian.
