The assumption that the channel is only opened upon synthetic device attach time no longer holds, e.g. Hyper-V network device MTU changes. We have to allow device drivers to preallocate bufrings, e.g. in attach DEVMETHOD, to prevent bufring allocation failure once the system memory is fragmented after running for a while. Sponsored by: Microsoft Differential Revision: https://reviews.freebsd.org/D7960 306073 hyperv/hn: Allocate bufrings in attach DEVMETHOD. So that reinitialization, e.g. MTU change, will not fail when the system memory is excessively fragmented.
