[PATCH for-next 8/8] net: hns: delete redundant broadcast packet filter process

[Salil Mehta <salil.mehta-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>]

From: Daode Huang <huangdaode-C8/M+/jPZTeaMJb+Lgu22Q@public.gmane.org>

The broadcast packets is filtered in the hardware now, so this process
is no need in the driver, just delete it.
