Use CSR_WRITE_1() to write RTK_TXSTART register because it is localted 

at an odd address (0xd9) and noted "8 bit" in rtl81x9reg.h.

XXX: FreeBSD and OpenBSD also use CSR_WRITE_1() to write RTK_GTXSTART
XXX: for 8169 even though there is a "16 bits" comment at GTXSTART macro.
XXX: Which is correct?
