John Audia 3eb08538c4 kernel: bump 6.6 to 6.6.46
This commit makes three changes all needed for the update of the 6.6 kernel.

1. Upstream kernel bump to 6.6.46

	Changelog: https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.6.46
	Manually rebased:
        	bcm27xx/patches-6.6/950-0320-spi-spidev-Restore-loading-from-Device-Tree.patch
	All other patches automatically rebased.

2. Adjusted the following for new ksym[1] enabling it:

        armsr/config-6.6
        bcm27xx/bcm2712/config-6.6

3. Added a fix to receiving fraglist GSO packets:

	generic/pending-6.6/601-udp-fix-receiving-fraglist-GSO_packets.patch[2]

Subject: [PATCH] net: dsa: bcm_sf2: enable GPHY for switch probing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
GPHY needs to be enabled to succesfully probe & setup switch port
connected to it. Otherwise hardcoding PHY OUI would be required.
Before:
brcm-sf2 80080000.switch lan4 (uninitialized): PHY [800c05c0.mdio--1:08] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan3 (uninitialized): PHY [800c05c0.mdio--1:09] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan2 (uninitialized): PHY [800c05c0.mdio--1:0a] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan1 (uninitialized): PHY [800c05c0.mdio--1:0b] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch wan (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 7
After:
brcm-sf2 80080000.switch lan4 (uninitialized): PHY [800c05c0.mdio--1:08] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan3 (uninitialized): PHY [800c05c0.mdio--1:09] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan2 (uninitialized): PHY [800c05c0.mdio--1:0a] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch lan1 (uninitialized): PHY [800c05c0.mdio--1:0b] driver [Generic PHY] (irq=POLL)
brcm-sf2 80080000.switch wan (uninitialized): PHY [800c05c0.mdio--1:0c] driver [Generic PHY] (irq=POLL)
