Minor overlapping changes in xfrm_device.c, between the double ESP trailing bug fix setting the XFRM_INIT flag and the changes in net-next preparing for bonding encryption support. Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-25hns: do not cast return value of napi_gro_receive to nullJason A. Donenfeld
Basically no drivers care about the return value here, and there's no __must_check that would make casting to void sensible, so remove it. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-18net: hns3: streaming dma buffer sync between cpu and deviceBarry Song
Right now they are empty functions for our SoC since hardware can keep cache coherent, but it is still good to align with streaming DMA APIs as device drivers should not make an assumption of SoC.

2020-06-18net: hns3: replace disable_irq by IRQ_NOAUTOEN flagBarry Song

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-04-25net: hns3: optimize the filter table entries handling when resettingJian Shen
Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

2020-04-25net: hns3: use mutex vport_lock instead of mutex umv_lockJian Shen
Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

2020-04-25net: hns3: refactor the promisc mode settingJian Shen
As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here. This patch removes the handle of overflow promisc from function hns3_set_rx_mode(), and updates the promisc mode in the service task.

2020-04-25net: hns3: refactor the MAC address configureJian Shen
Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.
