Before Google adopted FQ for its production servers, we had to ensure AF4 packets would get a higher share than BE1 ones. As discussed this week in Netconf 2023 in Paris, it is time to upstream this for public use. After this patch FQ can replace pfifo_fast, with the following differences : - FQ uses WRR instead of strict prio, to avoid starvation of low priority packets. - We make sure each band/prio tracks its own usage against sch->limit. This was done to make sure flood of low priority packets would not prevent AF4 packets to be queued. Contributed by Willem. - priomap can be changed, if needed (default value are the ones coming from pfifo_fast). In this patch, we set default band weights so that : - high prio (band=0) packets get 90% of the bandwidth if they compete with low prio (band=2) packets. - high prio packets get 75% of the bandwidth if they compete with medium prio (band=1) packets. Following patch in this series adds the possibility to tune the per-band weights. As we added many fields in 'struct fq_sched_data', we had to make sure to have the first cache line read-mostly, and avoid wasting precious cache lines. More optimizations are possible but will be sent separately. Signed-off-by:

A bulk transfer of the USB may contain many packets. And, the total number of the packets in the bulk transfer may be more than budget. Originally, only budget packets would be handled by napi_gro_receive(), and the other packets would be queued in the driver for next schedule. This patch would break the loop about getting next bulk transfer, when the budget is exhausted. That is, only the current bulk transfer would be handled, and the other bulk transfers would be queued for next schedule. Besides, the packets which are more than the budget in the current bulk trasnfer would be still queued in the driver, as the original method. In addition, a bulk transfer wouldn't contain more than 400 packets, so the check of queue length is unnecessary. Therefore, I replace it with WARN_ON_ONCE().

The recent support for DPLL introduced by commit 8a3a565f ("ice: add admin commands to access cgu configuration") and commit d7999f5e ("ice: implement dpll interface to control cgu") broke linking the ice driver if CONFIG_PTP_1588_CLOCK=n: ld: vmlinux.o: in function `ice_init_feature_support': (.text+0x8702b8): undefined reference to `ice_is_phy_rclk_present' ld: (.text+0x8702cd): undefined reference to `ice_is_cgu_present' ld: (.text+0x8702d9): undefined reference to `ice_is_clock_mux_present_e810t' ld: vmlinux.o: in function `ice_dpll_init_info_direct_pins': ice_dpll.c:(.text+0x894167): undefined reference to `ice_cgu_get_pin_freq_supp' ld: ice_dpll.c:(.text+0x894197): undefined reference to `ice_cgu_get_pin_name' ld: ice_dpll.c:(.text+0x8941a8): undefined reference to `ice_cgu_get_pin_type' ld: vmlinux.o: in function `ice_dpll_update_state': ice_dpll.c:(.text+0x894494): undefined reference to `ice_get_cgu_state' ld: vmlinux.o: in function `ice_dpll_init': (.text+0x8953d5): undefined reference to `ice_get_cgu_rclk_pin_info' The first commit broke things by calling functions in ice_init_feature_support that are compiled as part of ice_ptp_hw.o, including: * ice_is_phy_rclk_present * ice_is_clock_mux_present_e810t * ice_is_cgU_present The second commit continued the break by calling several CGU functions defined in ice_ptp_hw.c in the DPLL code. Because the ice_dpll.c file is compiled unconditionally, it will not link when CONFIG_PTP_1588_CLOCK=n. It might be possible to break this dependency and expose those functions without CONFIG_PTP_1588_CLOCK, but that is not clear to me. For the DPLL case, simply compile ice_dpll.o only when we have CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h The other functions are part of checking the netlist to see if hardware features are enabled. These checks don't really belong in ice_ptp_hw.c, and make more sense as part of the ice_common.c file. We already have ice_is_gps_in_netlist() in ice_common.c which is doing a similar check. Move the functions into ice_common.c and rename them to have the similar postfix of "in_netlist()" to be more expressive of what they are actually checking. This also makes the ice_find_netlist_node only called from within ice_common.c, so its safe to mark it static and stop declaring it in the ice_common.h header as well.

Newer versions of firmware will pre-reserve 1 VNIC for every possible PF and VF function. Update the driver logic to take this into account when assigning VNICs to the VFs. These pre-reserved VNICs for the inactive VFs should be subtracted from the global pool before assigning them to the active VFs. Not doing so may cause discrepancies that ultimately may cause some VFs to have insufficient VNICs to support features such as aRFS. Signed-off-by:
