Alex Elder says: ==================== net: ipa: miscellaneous cleanups This series contains some minor cleanups I've been meaning to get around to for a while. The first few remove the definitions of some currently-unused symbols. Several fix some warnings that are reported when the build is done with "W=2". All are simple and have no effect on the operation of the code. ==================== Signed-off-by: -
Alex Elder authored
In ipa_uc_response_hdlr() a comment uses the wrong function name when it describes where a clock reference is taken. Fix this. Also fix the comment in ipa_uc_response_hdlr() to correctly refer to ipa_uc_setup(), which is where the clock reference described here is taken. Signed-off-by:

When "W=2" is supplied to the build command, we get a warning about shadowing a global declaration (of a typedef) for a variable defined in ipa_probe(). Rename the variable to get rid of the warning. Signed-off-by:

Fix two spots where a variable "channel_id" is unnecessarily redefined inside loops in "gsi.c". This is warned about if "W=2" is added to the build command. Note that this problem is harmless, so there's no need to backport it as a bugfix. Remove a comment in gsi_init() about waking the system; the GSI interrupt does not wake the system any more.

The GSI general interrupt is managed by three registers: enable; status; and clear. The three registers have same set of field bits at the same locations. Use a common set of field masks for all three registers to avoid duplication. Signed-off-by:

The GSI interrupt type register and interrupt type mask register have the same field bits at the same locations. Use a common set of field masks for both registers rather than essentially duplicating them. The only place the interrupt mask register uses any of these is in gsi_irq_enable(). Signed-off-by:

Alex Elder authored
Most of the field masks used for fields in a status structure are unused. Remove their definitions; we can add them back again when we actually use them to handle arriving status messages. These are warned about if "W=2" is added to the build command. Signed-off-by:
-
Alex Elder authored
Only the deaggregation status exception type is ever actually used. If any other status exception type is reported we basically ignore it, and consume the packet. Remove the unused definitions of status exception type symbols; they can be added back when we actually handle them. Separately, two consecutive if statements test the same condition near the top of ipa_endpoint_suspend_one(). Instead, use a single test with a block that combines the previously-separate lines of code. Signed-off-by:

Three status opcodes are not currently supported. Symbols representing their numeric values are defined but never used. Remove those unused definitions; they can be defined again when they actually get used. Signed-off-by:
-
Alex Elder authored
In "gsi_trans.c", the field mask TRE_FLAGS_IEOB_FMASK is defined but never used. Although there's no harm in defining this, remove it for now and redefine it at some future date if it becomes needed. This is warned about if "W=2" is added to the build command. Signed-off-by:

The only usage of atmtcp_v_dev_ops is to pass its address to atm_dev_register() which takes a pointer to const, and comparing its address to another address, which does not modify it. Make it const to allow the compiler to put it in read-only memory. Signed-off-by:

similarly to what has been done with commit 9d149045 ("geneve: change from tx_error to tx_dropped on missing metadata"), avoid reporting errors to userspace in case the kernel doesn't find any tunnel information for a skb that is going to be transmitted: an increase of tx_dropped is enough. tested with the following script: # for t in ip6gre ip6gretap ip6erspan; do > ip link add dev gre6-test0 type $t external > ip address add dev gre6-test0 2001:db8::1/64 > ip link set dev gre6-test0 up > sleep 30 > ip -s -j link show dev gre6-test0 | jq \ > '.[0].stats64.tx | {"errors": .errors, "dropped": .dropped}' > ip link del dev gre6-test0 > done Reported-by:

Karsten Graul says: ==================== net/smc: introduce SMC-Dv2 support SMC-Dv2 support (see https://www.ibm.com/support/pages/node/6326337) provides multi-subnet support for SMC-D, eliminating the current same-subnet restriction. The new version detects if any of the virtual ISM devices are on the same system and can therefore be used for an SMC-Dv2 connection. Furthermore, SMC-Dv2 eliminates the need for PNET IDs on s390. ==================== Signed-off-by:

SMCD Version 2 allows to propose up to 8 additional ISM devices offered to the peer as candidates for SMCD communication. This patch covers determination of the ISM devices to be proposed. ISM devices without PNETID are preferred, since ISM devices with PNETID are a V1 leftover and will disappear over the time. Signed-off-by:

Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-09-28 This series contains updates to igb, igc, and e1000e drivers. Sven Auhagen adds XDP support for igb. Gal Hammer allows for 82576 to display part number string correctly for igb. Sasha adds device IDs for i221 and i226 parts. Exposes LPI counters and removes unused fields in structures for igc. He also adds Meteor Lake support for e1000e. For igc, Andre renames IGC_TSYNCTXCTL_VALID to IGC_TSYNCTXCTL_TXTT_0 to match the datasheet and adds a warning if it's not set when expected. Removes the PTP Tx timestamp check in igc_ptp_tx_work() as it's already checked in the watchdog_task. Cleans up some code by removing invalid error bits, renaming a bit to match datasheet naming, and removing a, now unneeded, macro. Vinicius makes changes for igc PTP: removes calling SYSTIMR to latch timer value, stores PTP time before a reset, and rejects schedules with times in the future. v2: Remove 'inline' from igb_xdp_tx_queue_mapping() and igb_rx_offset() for patch 1 ==================== Signed-off-by: -
