The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/net/ethernet/microchip/encx24j600 files follows
this syntax, but the content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc.
For e.g., running scripts/kernel-doc -none
drivers/net/ethernet/microchip/encx24j600_hw.h emits:
warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead
Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

1GbE Intel Wired LAN Driver Updates 2021-05-20
This series contains updates to igc driver only.
Andre Guedes says:
This series adds AF_XDP zero-copy feature to igc driver.
The initial patches do some code refactoring, preparing the code base to
land the AF_XDP zero-copy feature, avoiding code duplications. The last
patches of the series are the ones implementing the feature.
The last patch which indeed implements AF_XDP zero-copy support was
originally way too lengthy so, for the sake of code review, I broke it
up into two patches: one adding support for the RX functionality and the
other one adding TX support.
---
v2:
Patch 8/9 - "igc: Enable RX via AF_XDP zero-copy"
* In XDP_PASS flow, copy metadata too into the skb.
* When HW timestamp is added by the NIC, after copying it into
a local variable, update xdp_buff->data_meta so that
metadata length when XDP program is called 0.
* In igc_xdp_enable_pool(), call xsk_pool_dma_unmap() on
failure.
Known issues:
When an XDP application is running in Tx-Only mode with Zero-Copy
enabled, it is not expected to add the frames to the fill-queue. I have
noticed the following two issues in this scenario:
- If XDP_USE_NEED_WAKEUP flag is not set by application, igc_poll()
will go into infinite loop because the buffer allocation resulting
in igc_clean_rx_irq_zc() indicating that all work is not done and NAPI
should keep polling. This does not occur if XDP_USE_NEED_WAKEUP
flag is set.
- Since there are no buffers allocated by userspace for the fill
queue, there is no memory allocated for the NIC to copy the data
to. If the packet received is destined to the hardware queue where
XDP application is running, no packets are received even on other
queues.
Both these issues can be mitigated by adding a few frames to the
fill queue. The second issue can also be mitigated by making sure no
packets are being received on the hardware queue where Rx is running.

The skb_change_head() helper did not set "skb->mac_len", which is
problematic when it's used in combination with skb_redirect_peer().
Without it, redirecting a packet from a L3 device such as wireguard to
the veth peer device will cause skb->data to point to the middle of the
IP header on entry to tcp_v4_rcv() since the L2 header is not pulled
correctly due to mac_len=0.

To optimize it, create two new files "tm_pg", "tm_port" in tm directory
and use cat command to separately get info of pg and port.
The display style is below:
$ cat tm_pg
ID PRI_MAP MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S ...
00 0x1f dwrr 1 75 9 0 31 20 ...
$ cat tm_port
IR_B IR_U IR_S BS_B BS_S FLAG RATE(Mbps)
75 9 0 31 20 1 200000

Currently, the debugfs command for tm map is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create a single file
"tm_map" for it, and query it by command "cat tm_map",
return the result to userspace, rather than record in dmesg.
As user can't specify queue id in cat command, driver will return info
of all queue id.
The display style is below:
$ cat tm_map
queue_id qset_id pri_id tc_id
