Change Details

This allows access to the stats structure from elsewhere in the kernel. It is already exposed via R/W sysctl so this isn't a huge leap.

Currently there is no locking done to protect this structure. It is likely okay due to the low-volume nature of IGMP, but allows for the possibility of underflow. This appears to be one of the only holdouts of the conversion to counter(9) which was done for most protocol stat structures around 2013. This also updates the visibility of this stats structure so that it can be consumed from elsewhere in the kernel, consistent with the vast majority of VNET_PCPUSTAT structures.
