V4 changes:
  - Fixed a compilation issue: "txbd may be used uninitialized"

V3 changes:
  - Added documentation for all devargs in enetc4.rst.
  - Fixed kvlist memory leak issue.

V2 changes:
  - Fixed an un-used variable compilation issue reported on fedora:43-gcc-minsize
  - Fixed various AI reported issues:
	- Release notes updated for all new devargs
	- enect4.ini features doc updated for scattered RX.
	- removed Not required RTE_PTYPE_UNKNOWN.
	- Fixed mid-frame mbuf leak in SG case.
	- Enabled SG for enetc4 PF also.
	- move to calloc from rte_zmalloc in parse_txq_prior().
	- added vaidation checks on strdup, strtoul.
	- added NC devargs to use cacheable ops conditionally.
	- removed dead code like bd_base_p etc.
	- Fixed rte_cpu_to_le_16() conversion on flags and combined
	  all flags related patches in one patch.
	- Fixed memory leak issue due to TXQ priority patch.
  - There were some false positives, I have ignored them:
	Race condition on flags field:
		clean_tx_ring only touches HW-completed BDs (next_to_clean→hwci),
		never newly-submitted BDs; doorbell hasn't fired yet.
	Missing dcbf in clean_tx_ring:
		DPDK is single-threaded per queue; TX path always overwrites
		flags completely before dcbf.
	TX dcbf granularity with wrap:
		Safe (AI admits it).
	RX refill flush at wrap:
		In-loop dcbf at i & mask == 0 already flushes aligned groups;
		trailing flush only needed for partial groups.
	RX reading before invalidate:
		dccivac precedes the read for every group in the loop
