[TG3]: Fix 2nd ifup failure on 5752M.
This fixes a bug reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=7438
tg3_close() turns off the PHY if WoL and ASF are both disabled. On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.
This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.
Update version to 3.68.
