There's no explicit capability bit, so we just condition them on having efx->num_mac_stats >= MC_CMD_MAC_NSTATS_V2. Signed-off-by:

Medford2 NICs support more than MC_CMD_MAC_NSTATS stats, and report the new count in a field of MC_CMD_GET_CAPABILITIES_V4. This also means that the end generation count moves (it is, as before, the last 64 bits of the DMA buffer, but that is no longer MC_CMD_MAC_GENERATION_END). So read num_mac_stats from the GET_CAPABILITIES response, if present; otherwise assume MC_CMD_MAC_NSTATS; and always use num_mac_stats - 1 rather than MC_CMD_MAC_GENERATION_END. Signed-off-by:

Get rid of custom hex_dump_to_buffer(). The output is slightly changed, i.e. each byte followed by white space. Note, we don't use print_hex_dump() here since the original code uses nedev_dbg(). Signed-off-by:

Attaching more than one PHY to phylink is bad news, as we store a pointer to the PHY in a single location. Error out if more than one PHY is attempted to be attached. Signed-off-by:

The RGMII spec allows compliance for devices that implement an internal delay on TXC and/or RXC inside the transmitter. This patch adds the necessary RGMII_[RX|TX]ID mode code to handle such PHYs with the emac driver. Signed-off-by:

The ibm_emac driver predates the PHY_INTERFACE_MODE_* enums by a few years. And while the driver has been retrofitted to use the PHYLIB, the old definitions have stuck around to this day. This patch replaces all occurences of PHY_MODE_* with the respective equivalent PHY_INTERFACE_MODE_* enum. And finally, it purges the old macros for good. Signed-off-by:

phy_modes() in the common phy.h already defines the same phy mode names in lower case. The deleted rgmii_mode_name() is used only in one place and for a "notice-level" printk. Hence, it will not be missed. Signed-off-by:

Alexander Aring says: ==================== net: sched: sch: introduce extack support this patch series basically add support for extack in common qdisc handling. Additional it adds extack pointer to common qdisc callback handling this offers per qdisc implementation to setting the extack message for each failure over netlink. The extack message will be set deeper in qdisc functions but going not deeper as net core api. For qdisc module callback handling, the extack will not be set. This will be part of per qdisc extack handling. I also want to prepare patches to handle extack per qdisc module... so there will come a lot of more patches, just cut them down to make it reviewable. There are some above 80-chars width warnings, which I ignore because it looks more ugly otherwise. This patch-series based on patches by David Ahern which gave me some hints how to deal with extack support. Cc: David Ahern <dsahern@gmail.com> changes since v4: - rebase on current net-next/master - fix several typos (also David Ahren to Ahern, I am sorry) - Add acked by Jamal changes since v3: - remove patch 2/2 lib: nlattr: set extack msg if validate_nla fails since David Ahern has a better solution - Remove check on net admin permission since -EPERM indicates it already - Change rtab to "rate table" - this is what it's stands for - Fix cbs *not* support messages - Fix tcf block error message for allocation, allocation will be still there because there are multiple places which returns -ENOMEM - Finnally also took care about sch_atm, sorry somehow I forgot this one and I hope I didn't forgot any sch implementation to add new callback parameters changes since v2: - add fix coding style patch to catch all checkpatch warnings - add patch for setting netlink extack msg if validate_nla fails - changes in handle generic qdisc errors - remove NL_SET_ERR_MSG from memory allocation errors - remove NL_SET_ERR_MSG from device not found - change STAB to table size - add various new patches to add extack support for common TC functions like qdisc_get_rtab, tcf_block_get, qdisc_alloc and qdisc_create_dflt - users which are interessted in the detailed error messages can assign extack, otherwise NULL. - Add sch_cbq as example for qdisc_ops callback: init, qdisc_class_ops callbacks: change and graft - Add sch_cbs as example for qdisc_ops callback: change - Add sch_drr as example for qdisc_class ops callbacks: tcf_block ==================== Signed-off-by: -

This patch adds extack support for the function qdisc_create_dflt which is a common used function in the tc subsystem. Callers which are interested in the receiving error can assign extack to get a more detailed information why qdisc_create_dflt failed. The function qdisc_create_dflt will also call an init callback which can fail by any per-qdisc specific handling. Cc: David Ahern <dsahern@gmail.com> Acked-by:

When 1. an skb has no neighbour, and 2. skb->protocol is not IP[V6], we select the skb's cast type based on its destination MAC address. The multicast check is currently restricted to Multicast IP-mapped MACs. Extend it to also cover non-IP Multicast MACs. Signed-off-by:

Once all of qeth_l3_set_rx_mode()'s single-use helpers are folded back in, the two implementations actually look quite similar. So improve the readability by converting both set_rx_mode() routines to a common format. This also allows us to walk ip_mc_htable just once, instead of three times. Signed-off-by:

atomic_t variables are currently used to implement reference counters with the following properties: - counter is initialized to 1 using atomic_set() - a resource is freed upon counter reaching zero - once counter reaches zero, its further increments aren't allowed - counter schema uses basic atomic operations (set, inc, inc_not_zero, dec_and_test, etc.) Such atomic variables should be converted to a newly provided refcount_t type and API that prevents accidental counter overflows and underflows. This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable qeth_reply.refcnt is used as pure reference counter. Convert it to refcount_t and fix up the operations. Suggested-by:
