A context switch will force a call to flush_tlb_pending() (via
switch_to()), so if we test tlb_nr to be non-zero, then sleep, it
would become zero and later back at the original context we'll pass
zero down into the TLB flushing code which should never see a nr
argument of zero.

Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With
the full chip reset during MAC address change, the automatic PHY reset
during chip reset will cause a link down and bonding will not work
properly as a result. With this reset_phy parameter, we can do a chip
reset without link down when changing MAC address or MTU.

I was looking through the xfrm input/output code in order to abstract
out the address family specific encapsulation/decapsulation code.  During
that process I found this bug in the IP ID selection code in xfrm4_output.c.

At that point dst is still the xfrm_dst for the current SA which
represents an internal flow as far as the IPsec tunnel is concerned.
Since the IP ID is going to sit on the outside of the encapsulated
packet, we obviously want the external flow which is just dst->child.
