Re: [PATCH] vmxnet3: avoid assumption about invalid dma_pa in vmxnet3_set_mc()

vmxnet3_set_mc() still assumes zero is invalid pa:
  it assumes dma_mapping_error(...,0) returns true if vmxnet3_copy_mc() fails;
  it calls dma_unmap_single() iff new_table_pa is not zero.

The patch adds an explicit variable to track status of new_table_pa.

Please use "bool" and "true"/"false" for boolean variables.

Thanks.
