2019-10-31net: hns3: cleanup some print format warningGuojia Liao
Using '%d' for printing type unsigned int or '%u' for type int would cause static tools to give false warnings, so this patch cleanups this warning by using the suitable format specifier of the type of variable. BTW, modifies the type of some variables and macro to synchronize with their usage.

2019-10-31net: hns3: cleanup a format-truncation warningGuojia Liao
In hns3_nic_init_irq(), when '*_int_idx' has more than 9 digits and the length of netdev's name is IFNAMSIZ, the total length of final name will be bigger the HNAE3_INT_NAME_LEN - 1, even though '*_int_idx' will never have such large value, but the compiler gives a format-truncation warning for this case. So this patch just enlarges the length to avoid this warning. Signed-off-by: Guojia Liao <liaoguojia@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2019-10-31net: hns3: cleanup some magic numbersGuojia Liao
To make the code more readable, this patch replaces some magic numbers with macro or sizeof operation. Also uses macro lower_32_bits and upper_32_bits to get bits 0-31 and 32-63 of a number, instead of using type conversion and '>>' operation. No functional change.

2019-10-31net: hns3: add struct netdev_queue debug info for TX timeoutYunsheng Lin
When there is a TX timeout, we can tell if the driver or stack has stopped the queue by looking at state field, and when has the last packet transmited by looking at trans_start field. So this patch prints these two field in the hns3_get_tx_timeo_queue_info().

2019-10-31bnxt_en: Add support to collect crash dump via ethtoolVasundhara Volam
Driver supports 2 types of core dumps. 1. Live dump - Firmware dump when system is up and running. 2. Crash dump - Dump which is collected during firmware crash that can be retrieved after recovery. Crash dump is currently supported only on specific 58800 chips which can be retrieved using OP-TEE API only, as firmware cannot access this region directly. User needs to set the dump flag using following command before initiating the dump collection: $ ethtool -W|--set-dump eth0 N Where N is "0" for live dump and "1" for crash dump Command to collect the dump after setting the flag: $ ethtool -w eth0 data Filename v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n. Also change log message to netdev_info().

Sasha adds support for Intel client platforms Comet Lake and Tiger Lake to the e1000e driver. Also adds a fix for a compiler warning that was recently introduced, when CONFIG_PM_SLEEP is not defined, so wrap the code that requires this kernel configuration to be defined. Alex fixes a potential race condition between network configuration and power management for e1000e, which is similar to a past issue in the igb driver. Also provided a bit of code cleanup since the driver no longer checks for __E1000_DOWN.
