[PATCH 01/19] net/txgbe: fix hardware statistic rx_l3_l4_xsum_error

[Jiawen Wu]

Count the rx_l3_l4_xsum_error statistic in Rx path. Since this hardware
register counter is missing, resulted in the count always showing as 0
in error.

[PATCH 03/19] net/txgbe: reduce memory size of ring descriptors

[Jiawen Wu]

The memory of ring descriptors was allocated in size of the maximum ring
size. It seems not friendly to our hardware on some domestic platforms.
Change it to allocate in size of the real ring size.

[PATCH 05/19] net/txgbe: fix VF Rx buffer size in config register

[Jiawen Wu]

Refer to commit 8a3ef4b89e6d ("net/txgbe: fix Rx buffer size in
config register").

When round up buffer size to 1K, to configure the register, hardware
will receive packets exceeding the buffer size in LRO mode. It will
cause a segment fault in the receive function.

Since FDIR configuration is deprecated in generic ethdev device

to configure the FDIR parameters.

Two device arguments "pkt-filter-size" and "pkt-filter-drop-queue" are
added, they just continue to use the previous naming convention.

[PATCH 09/19] net/txgbe: fix the maxinum number of FDIR filter

[Jiawen Wu]

FDIR is determined the maximum value on the hardware based on the
memory space allocated (i.e. fdir_conf.pballoc). But the hash map of
FDIR is created based on TXGBE_MAX_FDIR_FILTER_NUM. These two do not
match. It resulted in the absence of error when creating more FDIR rules
than the maximum allowed by the hardware.

When FDIR flow rules are all cleared, FDIR mode is not cleared. This will
cause that creating new FDIR flow rules failed, for their mode are
different from the previously deleted ones.

[PATCH 12/19] net/txgbe: fix to create FDIR filter for tunnel SCTP packet

[Jiawen Wu]

This commit is the same as commit 0db38d54b57a ("net/txgbe: fix to
create FDIR filter for SCTP packet").

The check for the mask of SCTP item is repeated and wrong, fix it to

[PATCH 14/19] net/txgbe: fix FDIR rule raw relative for L3 packets

[Jiawen Wu]

Hardware supports FDIR flex field base setting from start of MAC header,
IP header, L4 header, L4 payload. So for IP packet which has no L4 header,
it cannot match the raw bytes with relative offset start from L3 payload.
And FDIR flex bytes rule cannot match L2 packets.

Therefore, we will declare that the relative offset is only used for
matching the L4 packets.

[PATCH 15/19] net/txgbe: fix FDIR input mask

[Jiawen Wu]

Fix FDIR mask settings to comply with the hardware configuration. And
mask out the spec field instead of manually setting it to 0.

There are some requirements of mask in hardware:
1) IPv4 mask should be little-endian.
2) Ipv6 source address mask has only 16 bits, one bit of mask
   corresponds to one byte of spec.
3) IPv6 dest address is only supported to perfect match the low 8 bits,
   so it is not taken into account for support in the driver.

[PATCH 16/19] net/txgbe: switch to use FDIR when ntuple filter is full

[Jiawen Wu]

Using ntuple filter has less performance loss on the hardware compared
to FDIR filter. So when the flow rule both match ntuple filter and FDIR
filter, ntuple filter will be created first. But there are only maximum
128 flow rules can be created on ntuple filter, it is far less than the
requirements of many users. So switch to use FDIR when ntuple filters
are full.

[PATCH 17/19] net/txgbe: fix VF-PF message for ntuple flow filter

[Jiawen Wu]

VF-PF message box is only cleared for the first 4 bytes when add a
ntuple filter. This does not present any actual errors in usage, but
there is issue in the code.

[PATCH 18/19] net/txgbe: switch to use FDIR on VF

[Jiawen Wu]

Switch to use FDIR when ntuple filters are full on VF, just like PF. And
VF should request PF driver to configure the FDIR rule on hardware, so
new PF-VF mailbox API version 2.3 is added to implement it.
