| | | | | | | | | | | | | | | | | | Currently, stmmac only supports 32 bits addressing for SKB. Enable the support for upto 48 bits addressing in XGMAC core. This avoids the use of bounce buffers and increases performance.

* net: stmmac: Add support for U32 TC filter using Flexible RX ParserJose Abreu2018-05-101-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for U32 filter by using an HW only feature called Flexible RX Parser. This allow us to match any given packet field with a pattern and accept/reject or even route the packet to a specific DMA channel. Right now we only support acception or rejection of frame and we only support simple rules. Though, the Parser has the flexibility of jumping to specific rules as an if condition so complex rules can be established. This is only supported in GMAC5.10+. The following commands can be used to test this code: 1) Setup an ingress qdisk: # tc qdisc add dev eth0 handle ffff: ingress 2) Setup a filter (e.g. filter by IP): # tc filter add dev eth0 parent ffff: protocol ip u32 match ip \ src 192.168.0.3 skip_sw action drop In every tests performed we always used the "skip_sw" flag to make sure only the RX Parser was involved.

* net: stmmac: Fix reception of Broadcom switches tagsFlorian Fainelli2018-01-221-1/+1
| | | | | | | | | | | | | | | | | | Broadcom tags inserted by Broadcom switches put a 4 byte header after the MAC SA and before the EtherType, which may look like some sort of 0 length LLC/SNAP packet (tcpdump and wireshark do think that way). With ACS enabled in stmmac the packets were truncated to 8 bytes on reception, whereas clearing this bit allowed normal reception to occur. In order to make that possible, we need to pass a net_device argument to the different core_init() functions and we are dependent on the Broadcom tagger padding packets correctly (which it now does). To be as little invasive as possible, this is only done for gmac1000 when the network device is DSA-enabled (netdev_uses_dsa() returns true).

So this patch replace speed/port by simpler speed10/speed100/speed1000/speed_mask variables. In dwmac4_core_init and dwmac1000_core_init, port/speed value was used directly without using the struct link. This patch convert also their usage to speedxxx.

| | | | | | | | | | | | | | | | | | | | Field FL/TPL in register TDES3 is not correctly set on GMAC4. TX appears to be functional on GMAC 4.10a even if this field is not set, however, to avoid relying on undefined behavior, set the length in TDES3. The field has a different meaning depending on if the TSE bit in TDES3 is set or not (TSO). However, regardless of the TSE bit, the field is not optional. The field is already set correctly when the TSE bit is set. Since there is no limit for the number of descriptors that can be used for a single packet, the field should be set to the sum of the buffers contained in: [<desc with First Descriptor bit set> ... <desc n> ... <desc with Last Descriptor bit set>], which should be equal to skb->len.

* net: stmmac: unify registers dumps methodsLABBE Corentin2017-02-241-2/+2
| | | | | | | | | | | | | | The stmmac driver have two methods for registers dumps: via ethtool and at init (if NETIF_MSG_HW is enabled). It is better to keep only one method, ethtool, since the other was ugly. This patch convert all dump_regs() function from "printing regs" to "fill the reg_space used by ethtool".

| | | | | | | | | | | | | The ethtool stat counter rx_crc from stmmac is mis-named, the name seems to speak about the number of RX CRC done, but in fact it is about errors. This patch rename it to rx_crc_errors, just like the same ifconfig counter.
