* bnxt_en: Ignore 0 value in autoneg supported speed from firmware.Michael Chan2017-03-091-2/+3
| | | | | | | | | | | In some situations, the firmware will return 0 for autoneg supported speed. This may happen if the firmware detects no SFP module, for example. The driver should ignore this so that we don't end up with an invalid autoneg setting with nothing advertised. When SFP module is inserted, we'll get the updated settings from firmware at that time.

| | | | | | | | | | The firmware call to do function reset is done too late. It is causing the rings that have been reserved to be freed. In NPAR mode, this bug is causing us to run out of rings.

| | | | | | | | | | | | If bnxt_hwrm_ring_free() is called during a failure path in bnxt_open(), it is possible that the completion rings have not been allocated yet. In that case, the completion doorbell has not been initialized, and calling bnxt_disable_int() will crash. Fix it by checking that the completion ring has been initialized before writing to the completion ring doorbell. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

| | | | | | | | | | | Add logic for an extra set of TX rings for XDP. If enabled, this set of TX rings equals the number of RX rings and shares the same IRQ as the RX ring set.

| | | | | | | | | | | | | | To support XDP_TX, we need to add a set of dedicated TX rings, each associated with the NAPI of an RX ring. To assign XDP rings and regular rings in a flexible way, we add a bp->tx_ring_map[] array to do the remapping. The netdev txq index is stored in the new field txq_index so that we can retrieve the netdev txq when handling TX completions.

Add a new function bnxt_reserve_rings() to centralize the logic. This will make it easier to add XDP_TX support which requires allocating a new set of TX rings.

* bnxt_en: Refactor rx SKB function.Michael Chan2017-02-071-14/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | Minor refactoring of bnxt_rx_skb() so that it can easily be replaced by a new function that handles packets in a single page. Also, use a function pointer bp->rx_skb_func() to switch to a new function when we add the new mode in the next patch. Add a new field data_ptr that points to the packet data in the bnxt_sw_rx_bd structure. The original data field is changed to void pointer so that it can either hold the kmalloc'ed data or a page pointer. The last parameter of bnxt_rx_skb() which was the length parameter is changed to include the payload offset of the packet in the upper 16 bit. The offset is needed to support the rx page mode and is not used in this existing function. v3: Added a new data_ptr parameter to bp->rx_skb_func(). The caller has the option to modify the starting address of the packet. This will be needed when XDP with headroom support is added. v2: Changed the name of the last parameter to offset_and_len to make the code more clear.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bnxt_update_link() is called from multiple code paths. Most callers, such as open, ethtool, already hold RTNL. Only the caller bnxt_sp_task() does not. So it is a bug to take RTNL inside bnxt_update_link(). Fix it by removing the RTNL inside bnxt_update_link(). The function now expects the caller to always hold RTNL. In bnxt_sp_task(), call bnxt_rtnl_lock_sp() before calling bnxt_update_link(). We also need to move the call to the end of bnxt_sp_task() since it will be clearing the BNXT_STATE_IN_SP_TASK bit. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In bnxt_sp_task(), we set a bit BNXT_STATE_IN_SP_TASK so that bnxt_close() will synchronize and wait for bnxt_sp_task() to finish. Some functions in bnxt_sp_task() require us to clear BNXT_STATE_IN_SP_TASK and then acquire rtnl_lock() to prevent race conditions. There are some bugs related to this logic. This patch refactors the code to have common bnxt_rtnl_lock_sp() and bnxt_rtnl_unlock_sp() to handle the RTNL and the clearing/setting of the bit. Multiple functions will need the same logic. We also need to move bnxt_reset() to the end of bnxt_sp_task(). Functions that clear BNXT_STATE_IN_SP_TASK must be the last functions to be called in bnxt_sp_task(). The common scheme will handle the condition properly. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
