Make ng_mppc to not disable the node in case of multiple packet loss. Quite often it can be just packet reorder, and killing link in such case is inconvenient. Add few sysctl's to control that behavior. PR: kern/182212 Submitted by: Eugene Grosbein Approved by: re (glebius)

Fix the parse type for NGM_LISTTYPES. Actually, text versions of generic commands are not used, since ngctl(8) uses binary messages for them. And to request a text command one needs a working ngctl(8). That's why the bug was never discovered. I'm pondering on removing the text support for generic commands. Found by: dim with clang 3.4

MFC 253346: PR: 168520 170096 Submitted by: adrian, zec Fix multiple kernel panics when VIMAGE is enabled in the kernel. These fixes are based on patches submitted by Adrian Chadd and Marko Zec. (1) Set curthread->td_vnet to vnet0 in device_probe_and_attach() just before calling device_attach(). This fixes multiple VIMAGE related kernel panics when trying to attach Bluetooth or USB Ethernet devices because curthread->td_vnet is NULL. (2) Set curthread->td_vnet in if_detach(). This fixes kernel panics when detaching networking interfaces, especially USB Ethernet devices. (3) Use VNET_DOMAIN_SET() in ng_btsocket.c (4) In ng_unref_node() set curthread->td_vnet. This fixes kernel panics when detaching Netgraph nodes.
