Hi all,
Commit a2941f6aa71a ("nvme: add command id quirk for apple controllers")
was merged to fix a regression in apple controllers that was introduced
after merging commit e7006de6c238 ("nvme: code command_id with a genctr
for use-after-free validation").

This series is comming to enable the same quirk for fabrics controllers
that used the command id index in the same way that was probably used in
apple controllers.

This series is a complementary series to NVMe-CLi and libnvme patches
that will introduce a new flag for "nvme connect" command:
"--skip-cid-gen". Using this flag will cause enabling
NVME_QUIRK_SKIP_CID_GEN quirk and will actually add the ability to
ignore the command id generation for other transport alongside PCI
transport.

default value of the flag is false.

Usage:
nvme connect -t <transport> -n <nqn> -a <addr> -s <sid> --skip-cid-gen
or
nvme connect -t <transport> -n <nqn> -a <addr> -s <sid> -p
