110 Function configuration
113 Users can configure one or more function attributes before enumerating the PCI
114 function. Usually it means, user should configure function attribute
115 before a bus specific device for the function is created. However, when
116 SRIOV is enabled, virtual function devices are created on the PCI bus.
117 Hence, function attribute should be configured before binding virtual
118 function device to the driver. For subfunctions, this means user should
119 configure port function attribute before activating the port function.
121 A user may set the hardware address of the function using
122 `devlink port function set hw_addr` command. For Ethernet port function
125 Users may also set the RoCE capability of the function using
126 `devlink port function set roce` command.
128 Users may also set the function as migratable using
129 `devlink port function set migratable` command.
131 Users may also set the IPsec crypto capability of the function using
132 `devlink port function set ipsec_crypto` command.
134 Users may also set the IPsec packet capability of the function using
135 `devlink port function set ipsec_packet` command.
137 Users may also set the maximum IO event queues of the function
138 using `devlink port function set max_io_eqs` command.
