net/ice: fix GTPU down/uplink and extension conflict
Checks
Commit Message
When adding a RSS rule with GTPU_DWN/UP, it will search profile
table from the top index. If a RSS rule with GTPU_EH already exists,
then GTPU_DWN/UP packet will match GTPU_EH profile. This patch solves
this issue by removing existed GTPU_EH rule before creating a new
GTPU_DWN/UP rule.
Fixes: 2e2810fc1868 ("net/ice: fix GTPU RSS")

Suggest interpret the relation ship bettween GTPU_EH_UPLINK/DWNLINK with
GTPU_EH to help knowledge the reason.

The naming "ice_gtpu_eh" is not clear, ice_hash_gtpu_eh_ctx?

I think you don't need to define struct for each pattern and set/unset
value for all of them, what you considate just 3 item, that are hdr,
hash filed and the pattern type, so you could just defined as below
struct ice_hash_gtpu_eh_ctx {
uint32_t pkt_hdr;
uint64_t hash_fld;
uint64_t hdr_hint; // for example: hdr =
ICE_FLOW_SEG_HDR_IPV4 | ICE_FLOW_SEG_HDR_UDP
}
and then only check this hdr_hint when set uplink/dwnlink
if(hdr & pf->gtpu_eh_ctx->hdr_hint)

No need to check !=DWN/UP here, EH/DWN/UP are mutual exclusion, they
also handler when parse pattern.

Alignment should match open parenthesis. Below is the same.

Is it better to use a local variable and then call ice_rem_rss_cfg one
time after if-else?
