r8169: shuffle some registers handling around (8168 operation only)
I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.
Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.
More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.
This code should not be the cause of regression for 810x and
8110 users.
