[PATCH] chelsio: working NAPI
This driver tries to enable/disable NAPI at runtime, but does so in an unsafe manner, and the NAPI interrupt handling is a mess. Replace it with a compile time selected NAPI implementation. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
