This reverts commit 3bda2e5df476417b6d08967e2d84234a59d57b1c. According to discussion with Andrew as follow: https://lore.kernel.org/netdev/09eda9fe-196b-006b-6f01-f54e75715961@huawei.com/ HNS3 driver needs to separate pause autoneg from general autoneg, so revert this incorrect patch.

octeontx2-af: Fix possible null pointer dereference.

octeontx2-af: Display all enabled PF VF rsrc_alloc entries.

2021-10-28T13:47:37Z

Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size.

net: ethernet: microchip: lan743x: Fix skb allocation failure

2021-10-28T13:45:07Z

The driver allocates skb during ndo_open with GFP_ATOMIC which has high chance of failure when there are multiple instances. GFP_KERNEL is enough while open and use GFP_ATOMIC only from interrupt context.

nfp: bpf: relax prog rejection for mtu check through max_pkt_offset

2021-10-28T11:59:32Z

MTU change is refused whenever the value of new MTU is bigger than the max packet bytes that fits in NFP Cluster Target Memory (CTM). However, an eBPF program doesn't always need to access the whole packet data. The maximum direct packet access (DPA) offset has always been caculated by verifier and stored in the max_pkt_offset field of prog aux data.
