This is incorrect. The valid values supported by the chip are 64, 128, 256, 512 only (power of 2 starting from 64). When the number of RX rings is greater than 128, the entry size will likely be wrong. Firmware will round down the invalid value (e.g. 192 rounded down to 128) provided by the driver, causing some RSS rings to not receive any packets. We already have an existing function bnxt_calc_nr_ring_pages() to do this calculation. Use it in bnxt_get_nr_rss_ctxs() to calculate the number of RSS contexts correctly for P5_PLUS chips.

The rings and buffers are initialized normally so that we can transmit and receive packets in loopback mode. That means page pool buffers are allocated for the aggregation ring just like the normal case. NAPI is not needed because we are just polling for the loopback packets. When we're done with the loopback tests, we call bnxt_half_close_nic() to clean up. When freeing the page pools, we hit a WARN_ON() in page_pool_unlink_napi() because the NAPI state linked to the page pool is uninitialized. The simplest way to avoid this warning is just to initialize the NAPIs during half open and delete the NAPIs during half close. Trying to skip the page pool initialization or skip linking of NAPI during half open will be more complicated.

Fix it by adding a bp->num_tc field to store the number of HW offload mqprio TCs for the device. Use bp->num_tc instead of netdev_get_num_tc(). This fixes a crash like this: BUG: kernel NULL pointer dereference, address: 0000000000000000 PGD 42b8404067 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 120 PID: 8661 Comm: ifconfig Kdump: loaded Tainted: G OE 5.18.16 #1 Hardware name: Lenovo ThinkSystem SR650 V3/SB27A92818, BIOS ESE114N-2.12 04/25/2023 RIP: 0010:bnxt_hwrm_cp_ring_alloc_p5+0x10/0x90 [bnxt_en] Code: 41 5c 41 5d 41 5e c3 cc cc cc cc 41 8b 44 24 08 66 89 03 eb c6 e8 b0 f1 7d db 0f 1f 44 00 00 41 56 41 55 41 54 55 48 89 fd 53 <48> 8b 06 48 89 f3 48 81 c6 28 01 00 00 0f b6 96 13 ff ff ff 44 8b RSP: 0018:ff65907660d1fa88 EFLAGS: 00010202 RAX: 0000000000000010 RBX: ff4dde1d907e4980 RCX: f400000000000000 RDX: 0000000000000010 RSI: 0000000000000000 RDI: ff4dde1d907e4980 RBP: ff4dde1d907e4980 R08: 000000000000000f R09: 0000000000000000 R10: ff4dde5f02671800 R11: 0000000000000008 R12: 0000000088888889 R13: 0500000000000000 R14: 00f0000000000000 R15: ff4dde5f02671800 FS: 00007f4b126b5740(0000) GS:ff4dde9bff600000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000416f9c6002 CR4: 0000000000771ee0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400 PKRU: 55555554 Call Trace: bnxt_hwrm_ring_alloc+0x204/0x770 [bnxt_en] bnxt_init_chip+0x4d/0x680 [bnxt_en] ? bnxt_poll+0x1a0/0x1a0 [bnxt_en] __bnxt_open_nic+0xd2/0x740 [bnxt_en] bnxt_open+0x10b/0x220 [bnxt_en] ? raw_notifier_call_chain+0x41/0x60 __dev_open+0xf3/0x1b0 __dev_change_flags+0x1db/0x250 dev_change_flags+0x21/0x60 devinet_ioctl+0x590/0x720 ? avc_has_extended_perms+0x1b7/0x420 ? _copy_from_user+0x3a/0x60 inet_ioctl+0x189/0x1c0 ? wp_page_copy+0x45a/0x6e0 sock_do_ioctl+0x42/0xf0 ? ioctl_has_perm.constprop.0.isra.0+0xbd/0x120 sock_ioctl+0x1ce/0x2e0 __x64_sys_ioctl+0x87/0xc0 do_syscall_64+0x59/0x90 ? syscall_exit_work+0x103/0x130 ? syscall_exit_to_user_mode+0x12/0x30 ? do_syscall_64+0x69/0x90 ? exc_page_fault+0x62/0x150 Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
