net: dsa: use ethtool string helpers

2024-11-03T18:36:34Z

These are the preferred way to copy ethtool strings. Avoids incrementing pointers all over the place. Signed-off-by: Rosen Penev (for hellcreek driver) Reviewed-by: Kurt Kanzenbach Link: https://patch.msgid.link/20241028044828.1639668-1-rosenp@gmail.com Signed-off-by: Jakub Kicinski

net: dsa: b53: fix jumbo frames on 10/100 ports

2024-10-08T08:42:27Z

All modern chips support and need the 10_100 bit set for supporting jumbo frames on 10/100 ports, so instead of enabling it only for 583XX enable it for everything except bcm63xx, where the bit is writeable, but does nothing. Tested on BCM53115, where jumbo frames were dropped at 10/100 speeds without the bit set.

net: dsa: b53: allow lower MTUs on BCM5325/5365

2024-10-08T08:42:27Z

While BCM5325/5365 do not support jumbo frames, they do support slightly oversized frames, so do not error out if requesting a supported MTU for them.

net: dsa: b53: fix max MTU for BCM5325/BCM5365

2024-10-08T08:42:27Z

BCM5325/BCM5365 do not support jumbo frames, so we should not report a jumbo frame mtu for them. But they do support so called "oversized" frames up to 1536 bytes long by default, so report an appropriate MTU.

net: dsa: b53: fix max MTU for 1g switches

2024-10-08T08:42:27Z

JMS_MAX_SIZE is the ethernet frame length, not the MTU, which is payload without ethernet headers. According to the datasheets maximum supported frame length for most gigabyte swithes is 9720 bytes, so convert that to the expected MTU when using VLAN tagged frames.

net: dsa: b53: fix jumbo frame mtu check

2024-10-08T08:42:27Z

JMS_MIN_SIZE is the full ethernet frame length, while mtu is just the data payload size. Comparing these two meant that mtus between 1500 and 1518 did not trigger enabling jumbo frames. So instead compare the set mtu ETH_DATA_LEN, which is equal to JMS_MIN_SIZE - ETH_HLEN - ETH_FCS_LEN; Also do a check that the requested mtu is actually greater than the minimum length, else we do not need to enable jumbo frames. In practice this only introduced a very small range of mtus that did not work properly. Newer chips allow 2000 byte large frames by default, and older chips allow 1536 bytes long, which is equivalent to an mtu of 1514. So effectivly only mtus of 1515~1517 were broken.

net: dsa: Switch back to struct platform_driver::remove()

2024-10-04T23:39:57Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/net/dsa to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Rather than print an error even when we get -EPROBE_DEFER, use dev_err_probe() to filter out those messages.
