* ethernet: chelsio: use eth_hw_addr_set()Jakub Kicinski2021-10-021-1/+2
| | | | | | | | Convert chelsio drivers from memcpy() and ether_addr_copy() to eth_hw_addr_set(). They lack includes. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* cxgb4vf: fix t4vf_eth_xmit()'s return typeLuc Van Oostenryck2020-06-281-1/+1
| | | | | | | | | | | The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'. Fix this by returning 'netdev_tx_t' in this driver too. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* cxgb4vf: Prefix adapter flags with CXGB4VFArjun Vynipadath2019-03-011-6/+6
| | | | | | | | | Some of these macros were conflicting with global namespace, hence prefixing them with CXGB4VF. Signed-off-by: Arjun Vynipadath <arjun@chelsio.com> Signed-off-by: Vishal Kulkarni <vishal@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* cxgb4/cxgb4vf: Program hash region for {t4/t4vf}_change_mac()Arjun Vynipadath2019-02-031-1/+2
| | | | | | | | | | | | | | {t4/t4_vf}_change_mac() API's were only doing additions to MPS_TCAM. This will fail, when the number of tcam entries is limited particularly in vf's. This fix programs hash region with the mac address, when TCAM addtion fails for {t4/t4vf}_change_mac(). Since the locally maintained driver list for hash entries is shared across mac_{sync/unsync}(), added an extra parameter if_mac to track the address added thorugh {t4/t4vf}_change_mac() Signed-off-by: Arjun Vynipadath <arjun@chelsio.com> Signed-off-by: David S.

* cxgb4vf: Synchronize access to mailboxHariprasad Shenai2016-06-251-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | The issue comes when there are multiple threads attempting to use the mailbox facility at the same time. The issue is the for the Virtual Function Driver, the only way to get the Virtual Interface statistics is to issue mailbox commands to ask the firmware for the VI Stats. And, because the VI Stats command can only retrieve a smallish number of stats per mailbox command, we have to issue three mailbox commands in quick succession. When ethtool or netstat command to get interface stats and interface up/down is run in a loop for every 0.1 sec, we observed mailbox collisions. And out of the two commands one would fail with the present code, since we don't queue the second command. To overcome the above issue, added a queue to access the mailbox. Whenever a mailbox command is issued add it to the queue. If its at the head issue the mailbox command, else wait for the existing command to complete. Usually command takes less than a milli-second to complete. Also timeout from the loop, if the command under execution takes long time to run. In reality, the number of mailbox access collisions is going to be very rare since no one runs such abusive script. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.
