myri10ge: get rid of custom busy poll code
Compared to custom busy_poll, the generic NAPI one is simpler and removes a lot of code. It removes one atomic in the fast path (when busy poll is not in action) since we do not have to use an extra spinlock. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

ated PCI/PCI-X to PCIe Bridges as being in the middle of the hierarchy, and when we tried to copy the pointer from link->parent->root, there was no parent, and we dereferenced a NULL pointer: BUG: unable to handle kernel NULL pointer dereference at 0000000000000090 IP: [<ffffffff9e424350>] pcie_aspm_init_link_state+0x170/0x820 Recognize that PCI/PCI-X to PCIe Bridges originate PCIe hierarchies just like Root Ports do, so link->root for these devices should also point to itself.
