Host (hcd_ci_fs.c):
- Release the speculatively-armed sibling BDT on the NAK path (IN only) as
well as on completion, so a NAKed multi-packet IN no longer leaks a BDT
that stays own=1 and blocks every same-direction pipe. Both paths now go
through a single release_sibling_bd() helper (was a copy-pasted disarm).
- Clear the ENTIRE shared BDT (both directions) on bus reset; clearing only
the IN half left a stale OUT/SETUP descriptor after a disconnect mid-OUT,
blocking the first control transfer on re-enumeration.
- Size bda[] to span the whole BDT (2*2*4) so STAT-indexed access is within
the declared array bounds (was out-of-declared-bounds, benign via union).
Shared (ci_fs_type.h):
- Hoist buffer_descriptor_t and the TOK_PID enum out of the device and host
drivers into the shared header so the identical definitions cannot drift.
Board (kinetis_k):
- Drop a redundant local in board_get_unique_id.
Build-verified: host + kinetis k/kl/k32l + MCX. HIL: frdm_k64f host 2/2
(cdc_msc_hid + device_info); frdm_kl25z device core suite green with the
relocated definitions.

A multi-packet OUT transfer speculatively arms both even/odd BDTs to avoid
NAK. When the host ends the transfer early with a short packet, the sibling
BDT was left armed (own=1), desyncing the even/odd ping-pong so the next OUT
packet landed at buffer+max_packet_size instead of buffer and the stack read
stale data. Disarm the sibling on completion.
Fixes device/mtp on Kinetis (GetDeviceInfo command was received into the wrong
buffer half -> hang). Pre-existing (MSC only arms single-packet command
receives so it never hit the double-buffer path). HIL: frdm_kl25z & frdm_k64f
device 13/13.
