When VFs need to be reconfigured dynamically after firmwware reset, the configuration sequence on the PF needs to be changed to register the VF buffers first. Otherwise, some VF firmware commands may not succeed as there may not be PF buffers ready for the re-directed firmware commands. This sequencing did not matter much before when we only supported the normal bring-up of VFs.

Refactor the hardware/firmware configuration portion in bnxt_sriov_enable() into a new function bnxt_cfg_hw_sriov(). This new function can be called after a firmware reset to reconfigure the VFs previously enabled. v2: straight refactor of the code. Reordering done in the next patch.

In preparation for the new firmware reset feature, some of the logic in bnxt_init_one() and related functions will be called again after firmware has reset. Reset some of the flags and capabilities so that everything that can change can be re-initialized. Refactor some functions to probe firmware versions and capabilities. Check some buffers before allocating as they may have been allocated previously. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If the silent parameter is set, suppress all messages when there is no response from firmware. When polling for firmware to come out of reset, no response may be normal and we want to suppress the error messages. Also, don't poll for the firmware DMA response if Bus Master is disabled. This is in preparation for error recovery when firmware may be in error or reset state or Bus Master is disabled. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

There are 4 functions handling message forwarding for SR-IOV. They check for non-zero firmware response code and then return -1. There is no need to do this anymore. The main messaging function will now return standard error code. Since we don't need to examine the response, we can use the hwrm_send_message() variant which will take the mutex automatically.

The main firmware messaging function returns the firmware defined error code and many callers have to convert to standard error code for proper propagation to userspace. Convert bnxt_hwrm_do_send_msg() to return standard error code so we can do away with all the special error code handling by the many callers.

Thomas Bogendoerfer says: ==================== ioc3-eth improvements In my patch series for splitting out the serial code from ioc3-eth by using a MFD device there was one big patch for ioc3-eth.c, which wasn't really usefull for reviews. This series contains the ioc3-eth changes splitted in smaller steps and few more cleanups. Only the conversion to MFD will be done later in a different series. Changes in v3: - no need to check skb == NULL before passing it to dev_kfree_skb_any - free memory allocated with get_page(s) with free_page(s) - allocate rx ring with just GFP_KERNEL - add required alignment for rings in comments Changes in v2: - use net_err_ratelimited for printing various ioc3 errors - added missing clearing of rx buf valid flags into ioc3_alloc_rings - use __func__ for printing out of memory messages ==================== Signed-off-by: NDavid S.

由 Gustavo A. R. Silva 提交于
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct spider_net_card { ... struct spider_net_descr darray[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct spider_net_card) + (tx_descriptors + rx_descriptors) * sizeof(struct spider_net_descr) with: struct_size(card, darray, tx_descriptors + rx_descriptors) Notice that, in this case, variable alloc_size is not necessary, hence it is removed.

Now mv88e6xxx does not enable its ports at setup itself and let the DSA core handle this, unused ports are disabled without being powered on first. While that is expected, the SERDES powering code was assuming that a port was already set up before powering it down, resulting in freeing an unused IRQ. The patch fixes this assumption.

Since .port_set_cmode is only called from mv88e6xxx_port_setup_mac and mv88e6xxx_phylink_mac_config, it is fine to keep this "make writable" code private to the mv88e6341_port_set_cmode implementation, instead of adding yet another operation to the switch info structure.

This is a follow-up patch for commit 17deaf5c ("net: dsa: mv88e6xxx: create serdes_get_lane chip operation"). The .serdes_get_lane implementations access the CMODE of a port, even though it is cached at the moment, it is safer to call them after the mutex is locked, not before. At the same time, check for an eventual error and return IRQ_DONE, instead of blindly ignoring it.
