2021-12-21net/mlx5e: Allow profile-specific limitation on max num of channelsTariq Toukan
Let SF/VF representor's netdev use profile-specific limitation on max_nch to reduce its memory and HW resources consumption. This is particularly important for environments with limited memory and high number of SFs.

2021-12-21net/mlx5e: Save memory by using dynamic allocation in netdev privTariq Toukan
Many arrays in priv are statically allocated with a pre-defined maximum (for num channels, num TCs, etc...), that is in some cases significantly larger than the actual maximum. Examples: - The more VFs are supported, the less MSIX vectors each of them could have. This limits the max_nch for each. - Systems with limited number of cores or MSIX (< 64). - Netdev profiles that do not support: QoS (DCB / HTB), PTP TX port timestamping. Here we save some amount of memory by moving several structures and arrays to follow the actual maximum instead. This patch also prepares the code for even more savings to follow. For example, on a system where the maximum num of channel is 8, the channels stats structs alone go down from 3648*64 = 228 KB to 3648*8 = 28.5 KB per interface. This is important for environments with high number of VFs/SFs or limited memory.

2021-12-21net/mlx5e: Add profile indications for PTP and QOS HTB featuresTariq Toukan
Let the profile indicate support of the PTP and HTB (QOS) features. This unifies the logic that calculates the number of netdev queues needed for the features, and allows simplification of mlx5e_create_netdev(), which no longer requires number of rx/tx queues as parameters.

hci_pause_advertising_sync shall always pause advertising until hci_resume_advertising_sync but instance 0x00 doesn't count in adv_instance_cnt so it was causing it to be skipped. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

This makes use of mgmt_alloc_skb to build MGMT_EV_DEVICE_CONNECTED so the data is copied directly to skb that is then sent using mgmt_send_event_skb eliminating the necessity of intermediary buffers.

2021-12-21hostfs: Fix writeback of dirty pagesSjoerd Simons
Hostfs was not setting up the backing device information, which means it uses the noop bdi. The noop bdi does not have the writeback capability enabled, which in turns means dirty pages never got written back to storage. In other words programs using mmap to write to files on hostfs never actually got their data written out... Fix this by simply setting up the bdi with default settings as all the required code for writeback is already in place.
