Current code will only warn and then dereference the NULL pointer or
continue, which results in a fatal NULL pointer dereference later.
If the initialization fails, the machine is unusable, so panic right

This patch makes sure that flow control packets initiated by the VF are
dropped and reported as spoofed.
Flow control packets can be used to limit the throughput or as DOS
attack when generated from a VF. Flow control is not supported per VF
hence any pause frames generated from a VF are considered malicious.
Also cleaned up indentation and some redundant comments.

Remove unused members in the PHY structure and add a new member to store
all the capabilities the PHY has as reported by the FW. This information
will help us determine what speeds the device is capable of when link is
down.
Also add an enum to decode the PHY types the NVM is capable of.
Use the phy_types variable to determine what phy types are possible
when link is down instead of device id as it will be more accurate.
When on a backplane device, we do not support changing any settings,
however we should display all the phy_types we are capable of so if we
see a backplane dev ID set supported and advertised purely based on
the phy_types variable.

Add a module_types variable to the link_info struct to save the module
information from get_phy_capabilities. This information can be used to
determine which speeds the module supports.
Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.
The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.
Use the new variable in ethtool to differentiate between a 10G/1G dual
speed fiber module and a 10G only module.

In some circumstances, the firmware may fail to allocate a VSI for a VF.
When this happens, the driver does not react well to the bad news and
has a panic attack.
To fix this problem, check the return value from i40e_alloc_vf_res and
don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this
bit will be in the proper state in the failure case, and won't blow up
elsewhere.

QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.
ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:
/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.
This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:
bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x
This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

If when reading a page we find a hole and our caller had already locked
the range (bio flags has the bit EXTENT_BIO_PARENT_LOCKED set), we end
up unlocking the hole's range and then later our caller unlocks it
again, which might have already been locked by some other task once
the first unlock happened.
Currently this can only happen during a call to the extent_same ioctl,
as it's the only caller of __do_readpage() that sets the bit
EXTENT_BIO_PARENT_LOCKED for bio flags.
Fix this by leaving the unlock exclusively to the caller.

Currently the clone ioctl allows to clone an inline extent from one file
to another that already has other (non-inlined) extents. This is a problem
because btrfs is not designed to deal with files having inline and regular
extents, if a file has an inline extent then it must be the only extent
in the file and must start at file offset 0. Having a file with an inline
extent followed by regular extents results in EIO errors when doing reads
or writes against the first 4K of the file.
Also, the clone ioctl allows one to lose data if the source file consists
of a single inline extent, with a size of N bytes, and the destination
file consists of a single inline extent with a size of M bytes, where we
have M > N. In this case the clone operation removes the inline extent
from the destination file and then copies the inline extent from the
source file into the destination file - we lose the M - N bytes from the
destination file, a read operation will get the value 0x00 for any bytes
in the the range [N, M] (the destination inode's i_size remained as M,
that's why we can read past N bytes).
So fix this by not allowing such destructive operations to happen and
return errno EOPNOTSUPP to user space.
Currently the fstest btrfs/035 tests the data loss case but it totally
ignores this - i.e. expects the operation to succeed and does not check
the we got data loss.
The following test case for fstests exercises all these cases that result
in file corruption and data loss:
