| | | | | | | | | | | | Use the appropriate function to flush correctly all entries. The old code does not remove the element from the hash table, only from the active queue.

* neta: Fix MTU change sequenceKornel Dulęba2022-09-011-2/+6
| | | | | | | | | | | | | | | | | The IFF_DRV_RUNNING flag is used to see if the interface needs to be temporarily brought down during MTU change sequence. The problem here is that this flag is cleared in mvneta_stop_locked, resulting in the reinitialization logic never being executed after MTU has been changed. Fix that by saving the flag value before the interface is brought down.

* mvneta: Fix MTU update sequenceKornel Duleba2021-09-281-19/+18
| | | | | | | | | | | | | | After MTU is updated we might start using allocating RX buffers from different pool. (MJUM9BYTES vs MCLBYTES) Because of that we need to update the RX buffer size in hardware. Previously it was done only when the interface was up, which is incorrect since MTU can be changed at any time.

| | | | | | | | | | | | It appears we must read MIB values as 2 4-byte words, lower address first. A single 8-byte MIB read returns the value with the lower 4 bytes copied into the upper 4 bytes, resulting in bogus byte counter values.

* Fix TX csum handling in if_mvnetaMarcin Wojtas2020-08-011-5/+2
| | | | | | | | | | | | | | | The mvneta device requires MVNETA_TX_CMD_L4_CHECKSUM_NONE bit to be set in the tx descriptor is checksum not required. However, mvneta_tx_set_csumflag() is not setting this flag currently, causing the hardware to randomly corrupt IP header during transmission. This affects injected IPv4 packets that skips kernel IP stack processing (e.g. DHCP), as well as all IPv6 packets, since the driver currently does not offload csum for IPv6. The fix is to remove all the early return paths from mvneta_tx_set_csumflag() which do not set the MVNETA_TX_CMD_L4_CHECKSUM_NONE flag.

* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-8/+9
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333

* Update mvneta/e6000sw for new DSA Device Tree BindingsMarcin Wojtas2019-03-231-12/+31
| | | | | | | | | | | | | | | | | | | In the latest Linux kernel revisions the DSA (Distributed Switch Architecture) device tree binding was changed. Instead of the top level dsa@ node, the switch and its ports is represented as a child node of the mdio bus. With that other modifications were added, such as relation with the ethernet port of the SoC. Adjust e6000sw etherswitch and mvneta drivers to that. Tested on Armada 3720 EspressoBin and Armada 388 Clearfog Pro boards.
