In current implementation, sg_set_buf is called to add buffers to sg
list which
is put into the virtqueue eventually.
The next sentence is somehow broken:
But there are some HighMem pages in
table->sgl can not get virtual address by sg_virt.
Maybe something like "But _if_ there are ... _you_ can not get ..."?
