As per the draft (https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header-06 ) LE value should be greater than or equal to SL.
what will happen if LE is less than SL?
I tested below combination in fd.io VPP version stable/1908 ( commit id :a6a98b5)
LE =0 & SL = 2 - SRv6 header processing is normal, there is no packet drop observe 
LE =1 & SL = 2 - SRv6 header processing is normal, there is no packet drop observe
LE =2 & SL = 2 - SRv6 header processing is normal, there is no packet drop observe
Based on the above observation, I understand LE value are not validated during the SRv6 packet processing. does my understanding is correct?
