alc b5407c1588 When sf_buf_alloc() replaces a virtual-to-physical mapping, it needn't
invalidate the TLB(s) if the old mapping wasn't used by the CPU.  With
network interfaces that implement checksum off-loading, the old mapping is
almost never used by the CPU, only by the device driver for setting up the
DMA operation.
