* cxgb4/cxgb4vf: fix flow control display for auto negotiationRahul Lakkireddy2019-12-301-7/+11
| | | | | | | | | | | | | | | | | As per 802.3-2005, Section Two, Annex 28B, Table 28B-2 [1], when _only_ Rx pause is enabled, both symmetric and asymmetric pause towards local device must be enabled. Also, firmware returns the local device's flow control pause params as part of advertised capabilities and negotiated params as part of current link attributes. So, fix up ethtool's flow control pause params fetch logic to read from acaps, instead of linkattr.

* cxgb4/cxgb4vf: Notify link changes to OS-dependent codeArjun Vynipadath2018-05-251-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a confusion of two different abstractions in the Common Code: Physical Link (Port) and Logical Network Interface (Virtual Interface), and we haven't been properly managing the state of the intersection of those two abstractions. On the one hand we have the Physical state of the Link -- up or down -- and on the other we have the logical state of the VI, enabled or not. {ethN} refers to both the Physical and Logical State. In this case, ifconfig only affects/interrogates the Logical State of a VI, and ethtool only deals with the Physical State. And these are different. So, just because we disable the VI, we don't really want to change the Physical Link Up/Down state. Thus, the previous hack to set "lc->link_ok = 0" when we disable a VI is completely incorrect. Where we get into trouble is where the Physical Link State and the Logical VI State cross swords. And that happens in t4_handle_get_port_info() where we need to manage/safe the Physical Link State, but we also need to know when the Logical VI State has changed and pass that back up to the OS-dependent Driver routine t4_os_link_changed() which is concerned about the Logical Interface. So we enable a VI and that causes Firmware to send us a new Port Information message, but if none of the Physical Link State particulars have changed, we don't call t4_os_link_changed(). This fix uses the existing OS Contract APIs for the Common Code to inform the OS-dependent portion of the Host Driver when the "Link" (really Logical Network Interface) is "up" or "down". A new API t4_enable_pi_params() is added which calls t4_enable_vi_params() and, if that is successful, then calls back to the OS Contract API t4_os_link_changed() notifying the OS-dependent layer of the potential Link State change.

* cxgb4vf: Synchronize access to mailboxHariprasad Shenai2016-06-251-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cxgb4vf: Add 40G support for cxgb4vf driverHariprasad Shenai2014-10-091-3/+7
| | | | | | | | | | | | | Add 40G support for cxgb4vf driver. ethtool speed values are just numbers of megabits and there is no SPEED_40000 in ethtool speed values. To be consistent, use integer constants directly for all speeds. Use is_x_10g_port()("is 10Gb/s or higher") in cfg_queues() instead of is_10g_port() ("is exactly 10Gb/s"). Else we will end up using a single "Queue Set" on 40Gb/s adapters. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* cxgb4: make functions static and remove dead codestephen hemminger2013-12-221-2/+2
| | | | | | | | | | Cleanup by making local functions static. The code to load config file is unreachable in net-next, probably came from some out of tree driver. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* drivers/net: fix up function prototypes after __dev* removalsGreg Kroah-Hartman2012-12-071-2/+1
| | | | | | | | | | | | The __dev* removal patches for the network drivers ended up messing up the function prototypes for a bunch of drivers. This patch fixes all of them back up to be properly aligned. Bonus is that this almost removes 100 lines of code, always a nice surprise.
