Description OSIDB Bzimport 2025-04-18 08:01:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

sfc: fix NULL dereferences in ef100_process_design_param()

Since cited commit, ef100_probe_main() and hence also
 ef100_check_design_params() run before efx->net_dev is created;
 consequently, we cannot netif_set_tso_max_size() or _segs() at this
 point.
Move those netif calls to ef100_probe_netdev(), and also replace
 netif_err within the design params code with pci_err.
