r8169: reset IntrStatus after chip reset
Original comment (Karsten): On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time after BIOS has run, IntrStatus reads 5 after chip has been reset. IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen after chip reset instead of before. Remark (Francois): Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR, the bug reveals itself with a typical "interrupt 0025 in poll" message at startup. In retrospect, the message should had been read as an hint of an unexpected hardware state several months ago :o( Fixes (at least part of) https://bugzilla.redhat.com/show_bug.cgi?id=460747 Signed-off-by: Karsten Wiese <fzu@wemgehoertderstaat.de> Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Tested-by: Josep <josep.puigdemont@gmail.com> Signed-off-by: David S.
