eth: fbnic: Add devlink dev flash support

2025-05-15T10:59:18Z

Add support to update the CMRT and control firmware as well as the UEFI driver on fbnic using devlink dev flash. Make sure the shutdown / quiescence paths like suspend take the devlink lock to prevent them from interrupting the FW flashing process.

eth: fbnic: add CONFIG_PTP_1588_CLOCK_OPTIONAL dependency

eth: fbnic: select DEVLINK and PAGE_POOL

fbnic: Change kconfig prompt from S390=n to !S390

2024-07-27T01:24:50Z

In testing the recent kernel I found that the fbnic driver couldn't be enabled on x86_64 builds. A bit of digging showed that the fbnic driver was the only one to check for S390 to be n, all others had checked for !S390. Since it is a boolean and not a tristate I am not sure it will be N. So just update it to use the !S390 flag. A quick check via "make menuconfig" verified that after making this change there was an option to select the fbnic driver.

eth: fbnic: don't build the driver when skb has more than 21 frags

2024-07-19T14:36:34Z

Similarly to commit 0e03c643dc93 ("eth: fbnic: fix s390 build."), the driver won't build if skb_shared_info has more than 25 frags assuming a 64B cache line and 21 frags assuming a 128B cache line.

Building the fbnic nn s390, yield a build bug: In function ‘fbnic_config_drop_mode_rcq’, inlined from ‘fbnic_enable’ at drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1836:4: ././include/linux/compiler_types.h:510:45: error: call to ‘__compiletime_assert_919’ declared with attribute error: FIELD_PREP: value too large for the field The relevant mask is 9 bits wide, and the related value is the cacheline aligned size of struct skb_shared_info. On s390 the cacheline size is 256 bytes, and skb_shared_info minimum size on 64 bits system is 320 bytes. Avoid building the driver for such arch.

eth: fbnic: Add link detection

2024-07-15T19:50:43Z

Add basic support for detecting the link and reporting it at the netdev layer. For now we will just use the values reporeted by the firmware as the link configuration and assume that is the current configuration of the MAC and PCS. With this we start the stubbing out of the phylink interface that will be used to provide the configuration interface for ethtool in a future patch set. The phylink interface isn't an exact fit. As such we are currently working around several issues in this patch set that we plan to address in the future such as: 1. Support for FEC 2. Support for multiple lanes to handle 50GbaseR2 vs 50GbaseR1 3.
