Seems this piece of code introduces a build error:

    drivers/net/vmxnet3/vmxnet3_rxtx.c: In function ‘vmxnet3_recv_pkts’:
    drivers/net/vmxnet3/vmxnet3_rxtx.c:635:18: error: variable ‘rxd’ set but not used [-Werror=unused-but-set-variable]
      Vmxnet3_RxDesc *rxd;
                      ^
    cc1: all warnings being treated as errors
    make[6]: *** [vmxnet3_rxtx.o] Error 1
