net: annotate data-races around dev->if_port

2024-05-09T01:51:30+00:00

Various ndo_set_config() methods can change dev->if_port dev->if_port is going to be read locklessly from rtnl_fill_link_ifmap(). Add corresponding WRITE_ONCE() on writer sides.

net: handle HAS_IOPORT dependencies

2024-04-08T10:56:56+00:00

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver.

3c515: remove unused 'mtu' variable

2024-04-06T05:10:59+00:00

This has never been used since the start of the git history. When building with W=1, the unused variable produces a gcc warning: drivers/net/ethernet/3com/3c515.c:35:18: error: 'mtu' defined but not used [-Werror=unused-const-variable=] Just remove it.

net: typhoon: implement ndo_features_check method

2022-02-05T15:34:46+00:00

Instead of disabling TSO at compile time if MAX_SKB_FRAGS > 32, implement ndo_features_check() method for this driver for a more dynamic handling. If skb has more than 32 frags and is a GSO packet, force software segmentation. Most locally generated packets will use a small number of fragments anyway. For forwarding workloads, we can limit gro_max_size at ingress, we might also implement gro_max_segs if needed. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller
