bnxt_en: Make PTP timestamp HWRM more silent
commit 056bce63c469 ("bnxt_en: Make PTP TX timestamp HWRM query silent") changed a netdev_err() to netdev_WARN_ONCE(). netdev_WARN_ONCE() is it generates a kernel WARNING, which is bad, for the following reasons: * You do not a kernel warning if the firmware queries are late * In busy networks, timestamp query failures fairly regularly * A WARNING message doesn't bring much value, since the code path is clear. (This was discussed in-depth in [1]) Transform the netdev_WARN_ONCE() into a netdev_warn_once(), and print a more well-behaved message, instead of a full WARN(). bnxt_en 0000:67:00.0 eth0: TS query for TX timer failed rc = fffffff5 [1] Link: https://lore.kernel.org/all/ZbDj%2FFI4EJezcfd1@gmail.com/ Signed-off-by: Breno Leitao <leitao@debian.org> Reviewed-by: Pavan Chebbi <pavan.chebbi@broadcom.com> Reviewed-by: Michael Chan <michael.chan@broadcom.com> Fixes: 056bce63c469 ("bnxt_en: Make PTP TX timestamp HWRM query silent") Link: https://lore.kernel.org/r/20240125134104.2045573-1-leitao@debian.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
