Add a flags field to struct efx_tx_buffer, replacing the continuation and map_single booleans. Since a single descriptor cannot be both a TSO header and the last descriptor for an skb, unionise efx_tx_buffer::{skb,tsoh} and add flags for validity of these fields. Clear all flags in free buffers (whereas previously the continuation flag would be set). Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>

The helper functions which translate IEEE MDIO Manageable Device (MMD) Energy-Efficient Ethernet (EEE) registers 3.20, 7.60 and 7.61 to and from the comparable ethtool supported/advertised settings will be needed by drivers other than those in PHYLIB (e.g. e1000e in a follow-on patch). In the same fashion as similar translation functions in linux/mii.h, move these functions from the PHYLIB core to the linux/mdio.h header file so the code will not have to be duplicated in each driver needing MMD-to-ethtool (and vice-versa) translations. The function and some variable names have been renamed to be more descriptive. Not tested on the only hardware that currently calls the related functions, stmmac, because I don't have access to any. Has been compile tested and the translations have been tested on a locally modified version of e1000e.

Currently the "bonding" driver does not support load balancing outgoing traffic in LACP mode for IPv6 traffic. IPv4 (and TCP or UDP over IPv4) are currently supported; this patch adds transmit hashing for IPv6 (and TCP or UDP over IPv6), bringing IPv6 up to par with IPv4 support in the bonding driver. In addition, bounds checking has been added to all transmit hashing functions. The algorithm chosen (xor'ing the bottom three quads of the source and destination addresses together, then xor'ing each byte of that result into the bottom byte, finally xor'ing with the last bytes of the MAC addresses) was selected after testing almost 400,000 unique IPv6 addresses harvested from server logs. This algorithm had the most even distribution for both big- and little-endian architectures while still using few instructions. Its behavior also attempts to closely match that of the IPv4 algorithm. The IPv6 flow label was intentionally not included in the hash as it appears to be unset in the vast majority of IPv6 traffic sampled, and the current algorithm not using the flow label already offers a very even distribution. Fragmented IPv6 packets are handled the same way as fragmented IPv4 packets, ie, they are not balanced based on layer 4 information. Additionally, IPv6 packets with intermediate headers are not balanced based on layer 4 information. In practice these intermediate headers are not common and this should not cause any problems, and the alternative (a packet-parsing loop and look-up table) seemed slow and complicated for little gain.

This change makes it so that if only the first 256 bytes of a buffer are used we just copy the data out and leave the offset and page count unchanged. There are multiple advantages to this. First it allows us to reuse the page much more in the case of pages larger than 4K. It also allows us to avoid some expensive atomic operations in the form of get_page/put_page. In perf I have seen CPU utilization for put_page drop from 3.5% to 1.8% as a result of this patch when doing small packet routing, and packet rates increased by about 3%.

This change makes it so that we do not use double buffering if the page size is larger than 4K. Instead we will simply walk through the page using up to 3K per receive, and if we receive less than we only move the offset by that amount. We will free the page when there is no longer any space left that we can use instead of checking the page count to see if we can cycle back to the start. The main motivation behind this is to avoid the unnecessary truesize cost for using a half page when most packets are 2K or smaller. With this new approach the largest possible truesize for a page fragment will be 3K when PAGE_SIZE is larger than 4K.

This change reverts an earlier patch that introduced ixgbe_init_rx_page_offset. The idea behind the function was to provide some variation in the starting offset for the page in order to reduce hot-spots in the cache. However it doesn't appear to provide any significant benefit in the testing I have done. It has however been a source of several bugs, and it blocks us from being able to use 2K fragments on larger page sizes. So the decision I made was to remove it.

Fix some issues around int variables used in data structures related to memory registration. Handle int overflow in mlx4_init_icm_table by using a u64 intermediate variable and changing struct mlx4_icm_table num_obj field to be u32. Change some more fields/variables to use u32 instead of int to prevent a case where the variable becomes negative when bit 31 is set. Also subtract log_mtts_per_seg from the exponent when computing num_mtt, since its added later on in that very same code area. This and the previous commit fixes some issues which actually prevent commit db5a7a65 ("mlx4_core: Scale size of MTT table with system RAM") from working. Now, when the number of MTTs is scaled with the size of the RAM we can map up to 8TB.

mlx4_buddy_init uses kmalloc() to allocate bitmaps, which fails when the required size is beyond the max supported value (or when memory is too fragmented to handle a huge allocation). Extend this to use use vmalloc() if kmalloc() fails, and take that into account when freeing the bitmaps as well. This fixes a driver load failure when log num mtt is 26 or higher, and is a step in the direction of allowing to register huge amounts of memory on large memory systems.

Add 6 new devices and one modified device, based on information from laptop vendor Windows drivers. Sony provides a driver with two new devices using a Gobi 2k+ layout (1199:68a5 and 1199:68a9). The Sony driver also adds a non-standard QMI/net interface to the already supported 1199:9011 Gobi device. We do not know whether this is an alternate interface number or an additional interface which might be present, but that doesn't really matter. Lenovo provides a driver supporting 4 new devices: - MC7770 (1199:901b) with standard Gobi 2k+ layout - MC7700 (0f3d:68a2) with layout similar to MC7710 - MC7750 (114f:68a2) with layout similar to MC7710 - EM7700 (1199:901c) with layout similar to MC7710 Note regaring the three devices similar to MC7710: The Windows drivers only support interface #8 on these devices. The MC7710 can support QMI/net functions on interface #19 and #20 as well, and this driver is verified to work on interface #19 (a firmware bug is suspected to prevent #20 from working). We do not enable these additional interfaces until they either show up in a Windows driver or are verified to work in some other way. Therefore limiting the new devices to interface #8 for now.

The driver has had its own interface number whitelisting code to simulate this functionality. Replace this with generic interface number matching now that the USB subsystem support is there. This - removes the need for a driver_info structure per interface number, - avoids running the probe function for unsupported interfaces, and - simplifies the code.
