whu@ cannot reproduce the assertion failure which led to these ifdefs being added in the first place, and since they appear wrong, i.e., the assertions ought to apply to all platforms, let's remove them.

- The BUS_DMA_KEEP_PG_OFFSET flag is needed, since storvsc_xferbuf_prepare() assumes that only the first segment may have a non-zero offset, and that all following segments are page-sized and -aligned. - storvsc_xferbuf_prepare() handles 64-bit bus addresses, so avoid unneeded bouncing on i386.

Changing the rsc_switch flag using sysctl to turn rsc on or off could hang. The orignal code sends request to host to get the mtu setting. Sometimes the host fails to reply, causing the thread to sleep forever waiting for the host response. Use existing cached mtu from hn device instead to avoid calling host.

An interface's bpf could feasibly not exist, in which case bpf_peers_present() would panic from a NULL pointer dereference. Solve this by adding a new IfAPI that could deal with a NULL bpf, if such could occur in the network stack. Reviewed by: zlei Sponsored by: Juniper Networks, Inc.

The allocation call could result in sleep lock violation if it is in smp_rendezvous. Move it out. Also move the pcpu memory pointer to vmbus_pcpu_data since it is only used on Hyper-V.

Add boot parameter hw.vmbus.tlb_hcall for tlb flush hypercall. By default it is set to 1 to allow hyercall tlb flush. It can be set to 0 in loader.conf to turn off hypercall and use system provided tlb flush routine. The change also changes flag in the per cpu contiguous memory allocation to no wait to avoid panic happened some cases which there are no enough contiguous memery available at boot time.
