If PAGE_SIZE is bigger than BNXT_RX_PAGE_SIZE, that means the native CPU page is bigger than the maximum length of the RX BD. Divide the page into multiple 32K buffers for the aggregation ring. Add an offset field in the bnxt_sw_rx_agg_bd struct to keep track of the page offset of each buffer. Since each page can be referenced by multiple buffer entries, call get_page() as needed to get the proper reference count.

The RX BD length field of this device is 16-bit, so the largest buffer size is 65535. For LRO and GRO, we allocate native CPU pages for the aggregation ring buffers. It won't work if the native CPU page size is 64K or bigger. We fix this by defining BNXT_RX_PAGE_SIZE to be native CPU page size up to 32K. Replace PAGE_SIZE with BNXT_RX_PAGE_SIZE in all appropriate places related to the rx aggregation ring logic. The next patch will add additional logic to divide the page into 32K chunks for aggrgation ring buffers if PAGE_SIZE is bigger than BNXT_RX_PAGE_SIZE.

On some dual port cards, link speeds on both ports have to be compatible. Firmware will inform the driver when a certain speed is no longer supported if the other port has linked up at a certain speed. Add logic to handle this event by logging a message and getting the updated list of supported speeds. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

Some hypervisors (e.g. ESX) require the VF MAC address to be forwarded to the PF for approval. In Linux PF, the call is not forwarded and the firmware will simply check and approve the MAC address if the PF has not previously administered a valid MAC address for this VF.

I added this check in setup_tc to multiple drivers, if (handle != TC_H_ROOT || tc->type != TC_SETUP_MQPRIO) Unfortunately restricting to TC_H_ROOT like this breaks the old instantiation of mqprio to setup a hardware qdisc. This patch relaxes the test to only check the type to make it equivalent to the check before I broke it. With this the old instantiation continues to work. A good smoke test is to setup mqprio with, # tc qdisc add dev eth4 root mqprio num_tc 8 \ map 0 1 2 3 4 5 6 7 \ queues 0@0 1@1 2@2 3@3 4@4 5@5 6@6 7@7 Fixes: e4c6734e ("net: rework ndo tc op to consume additional qdisc handle paramete") Reported-by: NSingh Krishneil <krishneil.k.singh@intel.com> Reported-by: NJake Keller <jacob.e.keller@intel.com> CC: Murali Karicheri <m-karicheri2@ti.com> CC: Shradha Shah <sshah@solarflare.com> CC: Or Gerlitz <ogerlitz@mellanox.com> CC: Ariel Elior <ariel.elior@qlogic.com> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> CC: Bruce Allan <bruce.w.allan@intel.com> CC: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Don Skidmore <donald.c.skidmore@intel.com> Signed-off-by: NJohn Fastabend <john.r.fastabend@intel.com> Signed-off-by: NDavid S.

Before this patch, we used a hardcoded value of 500 msec as the default value for firmware message response timeout. For better portability with future hardware or debug platforms, use the value provided by firmware in the first response and store it for all susequent messages. Redefine the macro HWRM_CMD_TIMEOUT to the stored value. Since we don't have the value yet in the first message, use the 500 ms default if the stored value is zero.

Allow the VF to setup its own MAC address if the PF has not administratively set it for the VF. To do that, we should always store the MAC address from the firmware. There are 2 cases: 1. The MAC address is valid. This MAC address is assigned by the PF and it needs to override the current VF MAC address. 2. The MAC address is zero. The VF will use a random MAC address by default. By storing this 0 MAC address in the VF structure, it will allow the VF user to change the MAC address later using ndo_set_mac_address() when it sees that the stored MAC address is 0. v2: Expanded descriptions and added more comments.

The arithmetic to zero pad the last 64-bit word in the push buffer is not correct. 1. It should be pdata + length to get to the end. 2. 'pdata' is void pointer and passing it to PTR_ALIGN() will cast the aligned pointer to void. Pass 'end' which is u64 pointer to PTR_ALIGN() instead so that the aligned pointer - 1 is the last 64-bit pointer to data.
