* qlxge: Derive both RSS keys from the common keyKevin Bowling2026-09-181-14/+13
| | | | | | | | | | | | | | Replace the embedded default with rss_getkey(). Preserve the ICB's little-endian representation of each big-endian key word, then copy the initial 16 bytes of the serialized IPv6 key into the IPv4 key. This retains the old default-key bytes and allows a configured common key to take effect. Leave RSS flags and queue mapping unchanged.

* chore: replace {0, 0} with {DEV,KOBJ}METHOD_ENDEnji Cooper2026-02-251-1/+1
| | | | | | | | | | | | | | Both of the aforementioned macros have been present in FreeBSD for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for `DEVMETHOD_END`. Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END` and `KOBJMETHOD_END` as appropriate. This helps ensure that future adaptations to drivers following patterns documented in driver(9) can be made more easily/without issue.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2715-15/+47
| | | | | | | | | | | | | | | 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

* Start process of removing the use of the deprecated "M_FLOWID" flagHans Petter Selasky2014-12-012-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from the FreeBSD network code. The flag is still kept around in the "sys/mbuf.h" header file, but does no longer have any users. Instead the "m_pkthdr.rsstype" field in the mbuf structure is now used to decide the meaning of the "m_pkthdr.flowid" field. To modify the "m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX" macros as defined in the "sys/mbuf.h" header file. This patch introduces new behaviour in the transmit direction. Previously network drivers checked if "M_FLOWID" was set in "m_flags" before using the "m_pkthdr.flowid" field. This check has now now been replaced by checking if "M_HASHTYPE_GET(m)" is different from "M_HASHTYPE_NONE". In the future more hashtypes will be added, for example hashtypes for hardware dedicated flows. "M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is valid and has no particular type. This change removes the need for an "if" statement in TCP transmit code checking for the presence of a valid flowid value. The "if" statement mentioned above is now a direct variable assignment which is then later checked by the respective network drivers like before. Additional notes: - The SCTP code changes will be committed as a separate patch. - Removal of the "M_FLOWID" flag will also be done separately. - The FreeBSD version has been bumped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | interface, in the r241616 a crutch was provided. It didn't work well, and finally we decided that it is time to break ABI and simply make if_baudrate a 64-bit value. Meanwhile, the entire struct if_data was reviewed. o Remove the if_baudrate_pf crutch. o Make all fields of struct if_data fixed machine independent size. The notion of data (packet counters, etc) are by no means MD. And it is a bug that on amd64 we've got a 64-bit counters, while on i386 32-bit, which at modern speeds overflow within a second. This also removes quite a lot of COMPAT_FREEBSD32 code. o Give 16 bit for the ifi_datalen field. This field was provided to make future changes to if_data less ABI breaking. Unfortunately the 8 bit size of it had effectively limited sizeof if_data to 256 bytes. o Give 32 bits to ifi_mtu and ifi_metric. o Give 64 bits to the rest of fields, since they are counters. __FreeBSD_version bumped.
