Enabled it compensates for the counters overflow but reduces performance and triggers error messages in HV setups. config FSL_FM_MAX_FRAME_SIZE int "Maximum L2 frame size" depends on FSL_FMAN range 64 9600 default "1522" help Configure this in relation to the maximum possible MTU of your network configuration. In particular, one would need to increase this value in order to use jumbo frames. FSL_FM_MAX_FRAME_SIZE must accomodate the Ethernet FCS (4 bytes) and one ETH+VLAN header (18 bytes), to a total of 22 bytes in excess of the desired L3 MTU. Note that having too large a FSL_FM_MAX_FRAME_SIZE (much larger than the actual MTU) may lead to buffer exhaustion, especially in the case of badly fragmented datagrams on the Rx path. Conversely, having a FSL_FM_MAX_FRAME_SIZE smaller than the actual MTU will lead to frames being dropped. This can be overridden by specifying "fsl_fm_max_frm" in the kernel bootargs: * in Hypervisor-based scenarios, by adding a "chosen" node with the "bootargs" property specifying "fsl_fm_max_frm="; * in non-Hypervisor-based scenarios, via u-boot's env, by modifying the "bootargs" env variable. config FSL_FM_RX_EXTRA_HEADROOM int "Add extra headroom at beginning of data buffers" depends on FSL_FMAN range 16 384 default "64" help Configure this to tell the Frame Manager to reserve some extra space at the beginning of a data buffer on the receive path, before Internal Context fields are copied. This is in addition to the private data area already reserved for driver internal use. The provided value must be a multiple of 16. This option does not affect in any way the layout of transmitted buffers. You may be required to enable the config option FMAN_RESOURCE_ALLOCATION_ALGORITHM and also FMAN_DISABLE_OH_TO_REUSE_RESOURCES to have enough resources when using this option and also supporting jumbo frames. This setting can be overridden by specifying "fsl_fm_rx_extra_headroom" in the kernel bootargs: * in Hypervisor-based scenarios, by adding a "chosen" node with the "bootargs" property specifying "fsl_fm_rx_extra_headroom="; * in non-Hypervisor-based scenarios, via u-boot's env, by modifying the "bootargs" env variable. endif # FSL_FMAN endmenu
