The old variant mangled the packet; that got fixed, but calculation itself got buggered. Restored the correct logics, fixed a subtle breakage we used to have even back then: if the sum is 0 mod 0xffff, we want to return 0, not 0xffff.

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.
