* dpaa2-eth: Release buffers back to pool on XDP_DROPIoana Ciocoi Radulescu2018-11-282-3/+33
| | | | | | | | | | | | | | Instead of freeing the RX buffers, release them back into the pool. We wait for the maximum number of buffers supported by a single release command to accumulate before issuing the command. Also, don't unmap the Rx buffers at the beginning of the Rx routine anymore, since that would require remapping them before release. Instead, just do a DMA sync at first and only unmap if the frame is meant for the stack. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: David S.

* dpaa2-eth: Add basic XDP supportIoana Ciocoi Radulescu2018-11-282-1/+194
| | | | | | | | | | | | | | We keep one XDP program reference per channel. The only actions supported for now are XDP_DROP and XDP_PASS. Until now we didn't enforce a maximum size for Rx frames based on MTU value. Change that, since for XDP mode we must ensure no scatter-gather frames can be received.

The driver has similar structure with other ASIX MAC drivers (AX88179), but with a number of important differences: - Driver supports both direct Phy and custom firmware interface for Phy programming. This is due to different firmware modules available with this product. - Driver handles new 2.5G/5G link speed configuration and reporting. - Device support all speeds from 100M up to 5G. - Device supports MTU up to 16K. Device supports various standard networking features, like checksum offloads, vlan tagging/filtering, TSO. The code of this driver is based on original ASIX sources and was extended by Aquantia for 5G multigig support. Patchset v2 includes following changes: - Function variables declarions fixed to reverse xmass tree - Improve patch layout structure - Remove unnecessary curly braces in switch/case statements - Use 'packed' attribute for HW structures only - Use eth_mac_addr function in set_mac_addr callback - Remove unnecessary 'memset' calls. - Read MAC address from EEPROM function has now better name - Use driver_priv field to store context. It avoids ugly cast. - Set max_mtu field. Remove check for MTU size - Rewrite read/write functions. Add helpers for read/write 16/32 bit values - Use mask and shifts instead of bitfields to support BE platforms. - Use stack allocated buffer for configuring mcast filters - Use AUTONEG_ENABLE when go to suspend state - Pad out wol_cfg field from context structure. Use stack allocated instead - Remove driver version - Check field 'duplex' in set_link_ksetting callback as well - Use already created defines in usb matching macro - Rename phy_ops struct to phy_cfg - Use ether_addr_copy for copying mac address - Add fall-through comment in switch/case for avoid checkpatch warning - Remove match for CDC ether device - Add ASIX's HW id-s to match this driver - Add all HW id-s with which driver can work to blacklist of cdc_ether driver Patchset v3 includes following changes: - Use linkmode_copy instead of bitmap_copy - Remove Direct PHY access code since production HW will not have this mode anymore - Fix line over 80 symbols and alignments in cdc_ether patch - Add match for ECM configuration On start our HW reports both ECM and vendor configs. Linux prefers to use ECM driver and chooses active configuration which is for ecm driver (not for vendor specific). We need to match this configuration and forcibly switch configuration to vendor specific. Patchset v4 includes following changes: - Set gso_max_size. - Optimize accessing to descriptors - Use SKB_TRUESIZE macro. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

However, the device cannot assign a VNI to such FIDs, which prevents the driver from supporting the enslavement of VxLAN devices to the VLAN-aware bridge. This patchset works around this limitation by emulating 802.1Q FIDs using 802.1D FIDs, which can be assigned a VNI and so far have only been used in conjunction with VLAN-unaware bridges. The downside of this approach is that multiple {Port,VID}->FID entries are required, whereas a single VID->FID entry is required with "true" 802.1Q FIDs. First four patches introduce the new FID family of emulated 802.1Q FIDs and the associated type of router interfaces (RIFs). Last patch flips the driver to use this new FID family. The diff is relatively small because the internal implementation of each FID family is contained and hidden in spectrum_fid.c. Different internal users (e.g., bridge, router) are aware of the different FID types, but do not care about their internal implementation. This makes it trivial to swap the current implementation of 802.1Q FIDs with the new one, using 802.1D FIDs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | Replace 802.1Q FIDs and VLAN RIFs with their emulated counterparts. The emulated 802.1Q FIDs are actually 802.1D FIDs and thus use the same flood tables, of per-FID type. Therefore, add 4K-1 entries to the per-FID flood tables for the new FIDs and get rid of the FID-offset flood tables that were used by the old 802.1Q FIDs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of "VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of "FID" type. In other words, the RIF type is derived from the underlying FID type. VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on top of 802.1D FIDs. Since the previous patch emulated 802.1Q FIDs using 802.1D FIDs, this patch emulates VLAN RIFs using FID RIFs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses 802.1Q FIDs when offloading a VLAN-aware bridge. Unfortunately, it is not possible to assign a VNI to such FIDs, which prompts the driver to forbid the enslavement of VxLAN devices to a VLAN-aware bridge. Workaround this hardware limitation by creating a new family of FIDs, emulated 802.1Q FIDs. These FIDs are emulated using 802.1D FIDs, which can be assigned a VNI. The downside of this approach is that multiple {Port, VID}->FID entries are required, whereas only a single VID->FID is required with "true" 802.1Q FIDs.
