net: stmmac: add support for hash table size 128/256 in dwmac4
1. get hash table size in hw feature reigster, and add support for taller hash table(128/256) in dwmac4. 2. only clear GMAC_PACKET_FILTER bits used in this function, to avoid side effect to functions of other bits. stmmac selftests output log with flow control on: ethtool -t eth0 The test result is PASS The test extra info: 1. MAC Loopback 0 2. PHY Loopback -95 3. MMC Counters 0 4. EEE -95 5. Hash Filter MC 0 6. Perfect Filter UC 0 7. MC Filter 0 8. UC Filter 0 9. Flow Control 0 Signed-off-by: Biao Huang <biao.huang@mediatek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
