* axge: Add support for AX88179ADamien Broka2023-10-111-8/+31
| | | | | | | | | | | | | | | The AX88179A has two firmware modes, one of which is backward compatible with existing AX88178A/179 driver. The active firmware mode can be controlled through a register. Update axge(4) man page to mention 179A support and ensure that, when bound to a AX88179A, the driver activates the compatible firmware mode.

* axge: Skip dummy packet headersDamien Broka2023-09-251-1/+18
| | | | | | | | | | | | | | | | | Newer versions of the AX88179 interweave dummies alongside valid packet headers in bulk IN transfer data. This was probably done for backward compatibility with existing drivers. However current driver records these dummy headers as dropped frames, leading to stats misreporting one Ierr per Ipkt. This skips those dummy headers silently, thereby not generating Ierrs for them.

| | | | | | | | | | | | | Create a wrapper for newbus to take giant and for busses to take it too. bus_topo_lock() should be called before interacting with newbus routines and unlocked with bus_topo_unlock(). If you need the topology lock for some reason, bus_topo_mtx() will provide that.

| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | axge_setmulti()/axge_setpromisc() with axge_rxfilter(). Multicast filter programming and promiscuous mode requires access to a common RX configuration register so there is no need to use separate functions with added complexity. axge_rxfilter() does not read back AXGE_RCR register since accessing a register in USB is too slow and we already have all knowledge of required configuration. Rebuilding RX filter configuration is simpler and faster than manipulating every bits after reading back the register. Note, axge_rxfilter() does not set RCR_IPE(IP header alignment on 32bit boundary) to disable extra padding bytes insertion. The extra padding wastes ethernet to USB host bandwidth as well as complicating RX handling logic. Current USB framework requires copying RX frames to mbufs so there is no need to worry about alignment. Previously axge_rx_frame() performed wrong bound check due to the extra padding and it was broken when RX checksum offloading is disabled. See added comment in axge_rx_frame () for actual RX packet layout. In axge_init(), disable WOL. It's meaningless to enable WOL in normal operation. In axge_rxeof(), use properly sized mbuf rather than blindly allocating a mbuf cluster. Use RX H/W checksum offloading only when administrator requested RX checksum offloading. Previously it always used RX H/W checksum offloading result regardless of RX checksum offloading state. Separate L4 checksum offloading validation from L3 one and properly set required offloading bits for each layer. This is to fix setting L4 checksum offloading bits for L3 packets. There are still lots of RX errors(probably RX FIFO overflows) under moderate load. Users are strongly recommended to enable ethernet flow control.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | structures. This simplifies mbuf copy operation to USB buffers as well as improving readability. The controller supports Microsoft LSOv1(aka TSO) but this change set does not include the support due to copying overhead to USB buffers and large amount of memory waste. Remove useless ZLP padding which seems to come from Linux. Required bits the code tried to set was not copied into USB buffer so it had no effect. Unlike Linux, FreeBSD USB stack automatically generates ZLP so no explicit padding is required in driver.[1] Micro-optimize updating IFCOUNTER_OPACKETS counter by moving it out of TX loop since updating counter is not cheap operation as it did long time ago and we already know how many number of packets were queued after exiting the loop. While here, fix a checksum offloading bug which will happen when upper stack computes checksum while H/W checksum offloading is active. The controller should be notified to not recompute the checksum in this case. Reviewed by: kevlo (initial version), hselasky Pointed out by: hselasky [1] Notes: svn path=/head/; revision=304326
